+Initial definitions
+-------------------
+
+The following symbol definitions rely on you knowing the translation that
+__virt_to_phys() does for your machine.  This macro converts the passed
+virtual address to a physical address.  Normally, it is simply:
+
+		phys = virt - PAGE_OFFSET + PHYS_OFFSET
+
+
+Decompressor Symbols
+--------------------
+
+ZTEXTADDR
+	Start address of decompressor.  There's no point in talking about
+	virtual or physical addresses here, since the MMU will be off at
+	the time when you call the decompressor code.  You normally call
+	the kernel at this address to start it booting.  This doesn't have
+	to be located in RAM, it can be in flash or other read-only or
+	read-write addressable medium.
+
+ZBSSADDR
+	Start address of zero-initialised work area for the decompressor.
+	This must be pointing at RAM.  The decompressor will zero initialise
+	this for you.  Again, the MMU will be off.
+
+ZRELADDR
+	This is the address where the decompressed kernel will be written,
+	and eventually executed.  The following constraint must be valid:
+
+		__virt_to_phys(TEXTADDR) == ZRELADDR
+
+	The initial part of the kernel is carefully coded to be position
+	independent.
+
+INITRD_PHYS
+	Physical address to place the initial RAM disk.  Only relevant if
+	you are using the bootpImage stuff (which only works on the old
+	struct param_struct).
+
+INITRD_VIRT
+	Virtual address of the initial RAM disk.  The following  constraint
+	must be valid:
+
+		__virt_to_phys(INITRD_VIRT) == INITRD_PHYS
+
+PARAMS_PHYS
+	Physical address of the struct param_struct or tag list, giving the
+	kernel various parameters about its execution environment.
+
+
+Kernel Symbols
+--------------
+
+PHYS_OFFSET
+	Physical start address of the first bank of RAM.
+
+PAGE_OFFSET
+	Virtual start address of the first bank of RAM.  During the kernel
+	boot phase, virtual address PAGE_OFFSET will be mapped to physical
+	address PHYS_OFFSET, along with any other mappings you supply.
+	This should be the same value as TASK_SIZE.
+
+TASK_SIZE
+	The maximum size of a user process in bytes.  Since user space
+	always starts at zero, this is the maximum address that a user
+	process can access+1.  The user space stack grows down from this
+	address.
+
+	Any virtual address below TASK_SIZE is deemed to be user process
+	area, and therefore managed dynamically on a process by process
+	basis by the kernel.  I'll call this the user segment.
+
+	Anything above TASK_SIZE is common to all processes.  I'll call
+	this the kernel segment.
+
+	(In other words, you can't put IO mappings below TASK_SIZE, and
+	hence PAGE_OFFSET).
+
+TEXTADDR
+	Virtual start address of kernel, normally PAGE_OFFSET + 0x8000.
+	This is where the kernel image ends up.  With the latest kernels,
+	it must be located at 32768 bytes into a 128MB region.  Previous
+	kernels placed a restriction of 256MB here.
+
+DATAADDR
+	Virtual address for the kernel data segment.  Must not be defined
+	when using the decompressor.
+
+VMALLOC_START
+VMALLOC_END
+	Virtual addresses bounding the vmalloc() area.  There must not be
+	any static mappings in this area; vmalloc will overwrite them.
+	The addresses must also be in the kernel segment (see above).
+	Normally, the vmalloc() area starts VMALLOC_OFFSET bytes above the
+	last virtual RAM address (found using variable high_memory).
+
+VMALLOC_OFFSET
+	Offset normally incorporated into VMALLOC_START to provide a hole
+	between virtual RAM and the vmalloc area.  We do this to allow
+	out of bounds memory accesses (eg, something writing off the end
+	of the mapped memory map) to be caught.  Normally set to 8MB.
+
+Architecture Specific Macros
+----------------------------
+
+BOOT_MEM(pram,pio,vio)
+	`pram' specifies the physical start address of RAM.  Must always
+	be present, and should be the same as PHYS_OFFSET.
+
+	`pio' is the physical address of an 8MB region containing IO for
+	use with the debugging macros in arch/arm/kernel/debug-armv.S.
+
+	`vio' is the virtual address of the 8MB debugging region.
+
+	It is expected that the debugging region will be re-initialised
+	by the architecture specific code later in the code (via the
+	MAPIO function).
+
+BOOT_PARAMS
+	Same as, and see PARAMS_PHYS.
+
+FIXUP(func)
+	Machine specific fixups, run before memory subsystems have been
+	initialised.
+
+MAPIO(func)
+	Machine specific function to map IO areas (including the debug
+	region above).
+
+INITIRQ(func)
+	Machine specific function to initialise interrupts.

+Too many problems poped up because of unnoticed misaligned memory access in
+kernel code lately.  Therefore the alignment fixup is now unconditionally
+configured in for SA11x0 based targets.  According to Alan Cox, this is a
+bad idea to configure it out, but Russell King has some good reasons for
+doing so on some f***ed up ARM architectures like the EBSA110.  However
+this is not the case on many design I'm aware of, like all SA11x0 based
+ones.
+
+Of course this is a bad idea to rely on the alignment trap to perform
+unaligned memory access in general.  If those access are predictable, you
+are better to use the macros provided by include/asm/unaligned.h.  The
+alignment trap can fixup misaligned access for the exception cases, but at
+a high performance cost.  It better be rare.
+
+Now for user space applications, it is possible to configure the alignment
+trap to SIGBUS any code performing unaligned access (good for debugging bad
+code), or even fixup the access by software like for kernel code.  The later
+mode isn't recommended for performance reasons (just think about the
+floating point emulation that works about the same way).  Fix your code
+instead!
+
+Please note that randomly changing the behaviour without good thought is
+real bad - it changes the behaviour of all unaligned instructions in user
+space, and might cause programs to fail unexpectedly.
+
+To change the alignment trap behavior, simply echo a number into
+/proc/sys/debug/alignment.  The number is made up from various bits:

+---		-----------------
+
+0		A user process performing an unaligned memory access
+		will cause the kernel to print a message indicating
+		process name, pid, pc, instruction, address, and the
+		fault code.
+
+1		The kernel will attempt to fix up the user process
+		performing the unaligned access.  This is of course
+		slow (think about the floating point emulator) and
+		not recommended for production use.
+
+2		The kernel will send a SIGBUS signal to the user process
+		performing the unaligned access.
+
+Note that not all combinations are supported - only values 0 through 5.
+(6 and 7 don't make sense).
+
+For example, the following will turn on the warnings, but without
+fixing up or sending SIGBUS signals:
+
+	echo 1 > /proc/sys/debug/alignment
+
+You can also read the content of the same file to get statistical
+information on unaligned access occurrences plus the current mode of

+		Kernel Memory Layout on ARM Linux
+
+		Russell King <rmk@arm.linux.org.uk>
+			April 27, 2003 (2.5.68)
+
+This document describes the virtual memory layout which the Linux
+kernel uses for ARM processors.  It indicates which regions are
+free for platforms to use, and which are used by generic code.
+
+The ARM CPU is capable of addressing a maximum of 4GB virtual memory
+space, and this must be shared between user space processes, the
+kernel, and hardware devices.
+
+As the ARM architecture matures, it becomes necessary to reserve
+certain regions of VM space for use for new facilities; therefore
+this document may reserve more VM space over time.
+
+Start		End		Use
+--------------------------------------------------------------------------
+ffff8000	ffffffff	copy_user_page / clear_user_page use.
+				For SA11xx and Xscale, this is used to
+				setup a minicache mapping.
+
+ffff1000	ffff7fff	Reserved.
+				Platforms must not use this address range.
+
+ffff0000	ffff0fff	CPU vector page.
+				The CPU vectors are mapped here if the
+				CPU supports vector relocation (control
+				register V bit.)
+
+ffe00000	fffeffff	Free for platform use, not recommended.
+
+ffc00000	ffdfffff	2MB consistent memory mapping.
+				Memory returned by the consistent_alloc
+				low level function will be dynamically
+				mapped here.
+
+ff000000	ffbfffff	Free for platform use, not recommended.
+
+VMALLOC_END	ff000000	Free for platform use, recommended.
+
+VMALLOC_START	VMALLOC_END	vmalloc() / ioremap() space.
+				Memory returned by vmalloc/ioremap will
+				be dynamically placed in this region.
+				VMALLOC_START may be based upon the value
+				of the high_memory variable.
+
+PAGE_OFFSET	high_memory	Kernel direct-mapped RAM region.
+				This maps the platforms RAM, and typically
+				maps all platform RAM in a 1:1 relationship.
+
+TASK_SIZE	PAGE_OFFSET	Kernel module space
+				Kernel modules inserted via insmod are
+				placed here using dynamic mappings.
+
+00001000	TASK_SIZE	User space mappings
+				Per-thread mappings are placed here via
+				the mmap() system call.
+
+00000000	00000fff	CPU vector page / null pointer trap
+				CPUs which do not support vector remapping
+				place their vector page here.  NULL pointer
+				dereferences by both the kernel and user
+				space are also caught via this mapping.
+
+Please note that mappings which collide with the above areas may result
+in a non-bootable kernel, or may cause the kernel to (eventually) panic
+at run time.
+
+Since future CPUs may impact the kernel mapping layout, user programs
+must not access any memory which is not mapped inside their 0x0001000
+to TASK_SIZE address range.  If they wish to access these areas, they
+must set up their own mappings using open() and mmap().

+drivers or other part of the kernel that need to be informed of
+policy changes (ex. thermal modules like ACPI) or of all
+frequency changes (ex. timing code) or even need to force certain
+speed limits (like LCD drivers on ARM architecture). Additionally, the
+kernel "constant" loops_per_jiffy is updated on frequency changes
+here.
+
+Reference counting is done by cpufreq_get_cpu and cpufreq_put_cpu,
+which make sure that the cpufreq processor driver is correctly
+registered with the core, and will not be unloaded until
+cpufreq_put_cpu is called.
+
+2. CPUFreq notifiers
+====================
+
+CPUFreq notifiers conform to the standard kernel notifier interface.
+See linux/include/linux/notifier.h for details on notifiers.
+
+There are two different CPUFreq notifiers - policy notifiers and
+transition notifiers.
+
+
+2.1 CPUFreq policy notifiers
+----------------------------
+
+These are notified when a new policy is intended to be set. Each
+CPUFreq policy notifier is called three times for a policy transition:
+
+1.) During CPUFREQ_ADJUST all CPUFreq notifiers may change the limit if
+    they see a need for this - may it be thermal considerations or
+    hardware limitations.
+
+2.) During CPUFREQ_INCOMPATIBLE only changes may be done in order to avoid
+    hardware failure.
+
+3.) And during CPUFREQ_NOTIFY all notifiers are informed of the new policy
+   - if two hardware drivers failed to agree on a new policy before this
+   stage, the incompatible hardware shall be shut down, and the user
+   informed of this.
+
+The phase is specified in the second argument to the notifier.
+
+The third argument, a void *pointer, points to a struct cpufreq_policy
+consisting of five values: cpu, min, max, policy and max_cpu_freq. min 
+and max are the lower and upper frequencies (in kHz) of the new
+policy, policy the new policy, cpu the number of the affected CPU or
+CPUFREQ_ALL_CPUS for all CPUs; and max_cpu_freq the maximum supported
+CPU frequency. This value is given for informational purposes only.
+
+
+2.2 CPUFreq transition notifiers
+--------------------------------
+
+These are notified twice when the CPUfreq driver switches the CPU core
+frequency and this change has any external implications.
+
+The second argument specifies the phase - CPUFREQ_PRECHANGE or
+CPUFREQ_POSTCHANGE.
+
+The third argument is a struct cpufreq_freqs with the following
+values:
+cpu	- number of the affected CPU or CPUFREQ_ALL_CPUS
+old	- old frequency
+new	- new frequency

+
+
+
+1. What To Do?
+==============
+
+So, you just got a brand-new CPU / chipset with datasheets and want to
+add cpufreq support for this CPU / chipset? Great. Here are some hints
+on what is neccessary:
+
+
+1.1 Initialization
+------------------
+
+First of all, in an __initcall level 7 or later (preferrably
+module_init() so that your driver is modularized) function check
+whether this kernel runs on the right CPU and the right chipset. If
+so, register a struct cpufreq_driver with the CPUfreq core using
+cpufreq_register_driver()
+
+What shall this struct cpufreq_driver contain? 
+
+cpufreq_driver.name -		The name of this driver.
+
+cpufreq_driver.init -		A pointer to the per-CPU initialization 
+				function.
+
+cpufreq_driver.verify -		A pointer to a "verfication" funciton.
+
+cpufreq_driver.setpolicy _or_ 
+cpufreq_driver.target -		See below on the differences.
+
+And optionally
+
+cpufreq_driver.exit -		A pointer to a per-CPU cleanup function.
+
+cpufreq_driver.attr -		A pointer to a NULL-terminated list of
+				"struct freq_attr" which allow to
+				export values to sysfs.
+
+
+1.2 Per-CPU Initialization
+--------------------------
+
+Whenever a new CPU is registered with the device model, or after the
+cpufreq driver registers itself, the per-CPU initialization fucntion 
+cpufreq_driver.init is called. It takes a struct cpufreq_policy
+*policy as argument. What to do now?
+
+If necessary, activate the CPUfreq support on your CPU (unlock that
+register etc.).
+
+Then, the driver must fill in the following values:
+
+policy->cpuinfo.min_freq _and_
+policy->cpuinfo.max_freq -	the minimum and maximum frequency 
+				(in kHz) which is supported by 
+				this CPU
+policy->cpuinfo.transition_latency   the time it takes on this CPU to
+				switch between two frequencies (if
+				appropriate, else specify
+				CPUFREQ_ETERNAL)
+
+policy->cur			The current operating frequency of
+				this CPU (if appropriate)
+policy->min, 
+policy->max, 
+policy->policy and, if neccessary,
+policy->governor		must contain the "default policy" for
+				this CPU. A few moments later,
+				cpufreq_driver.verify and either
+				cpufreq_driver.setpolicy or
+				cpufreq_driver.target is called with
+				these values.
+
+For setting some of these values, the frequency table helpers might be
+helpful. See the section 2 for more information on them.
+
+
+1.3 verify
+------------
+
+When the user decides a new policy (consisting of
+"policy,governor,min,max") shall be set, this policy must be validated
+so that incompatible values can be corrected. For verifying these
+values, a frequency table helper and/or the
+cpufreq_verify_within_limits(struct cpufreq_policy *policy, unsigned
+int min_freq, unsigned int max_freq) function might be helpful. See
+section 2 for details on frequency table helpers.
+
+You need to make sure that at least one valid frequency (or operating
+range) is within policy->min and policy->max. If necessary, increase
+policy->max fist, and only if this is no solution, decreas policy->min.
+
+
+1.4 target or setpolicy?
+----------------------------
+
+Most cpufreq drivers or even most cpu frequency scaling algorithms 
+only allow the CPU to be set to one frequency. For these, you use the
+->target call.
+
+Some cpufreq-capable processors switch the frequency between certain
+limits on their own. These shall use the ->setpolicy call
+
+
+1.4. target
+-------------
+
+The target call has three arguments: struct cpufreq_policy *policy,
+unsigned int target_frequency, unsigned int relation.
+
+The CPUfreq driver must set the new frequency when called here. The
+actual frequency must be determined using the following rules:
+
+- keep close to "target_freq"
+- policy->min <= new_freq <= policy->max (THIS MUST BE VALID!!!)
+- if relation==CPUFREQ_REL_L, try to select a new_freq higher than or equal
+  target_freq. ("L for lowest, but no lower than")
+- if relation==CPUFREQ_REL_H, try to select a new_freq lower than or equal
+  target_freq. ("H for highest, but no higher than")
+
+Here again the frequency table helper might assist you - see section 3
+for details.
+
+
+1.5 setpolicy
+---------------
+
+The setpolicy call only takes a struct cpufreq_policy *policy as
+argument. You need to set the lower limit of the in-processor or
+in-chipset dynamic frequency switching to policy->min, the upper limit
+to policy->max, and -if supported- select a performance-oriented
+setting when policy->policy is CPUFREQ_POLICY_PERFORMANCE, and a
+powersaving-oriented setting when CPUFREQ_POLICY_POWERSAVE. Also check
+the reference implementation in arch/i386/kernel/cpu/cpufreq/longrun.c
+
+
+
+2. Frequency Table Helpers
+==========================
+
+As most cpufreq processors only allow for being set to a few specific
+frequencies, a "frequency table" with some functions might assist in
+some work of the processor driver. Such a "frequency table" consists
+of an array of struct cpufreq_freq_table entries, with any value in
+"index" you want to use, and the corresponding frequency in
+"frequency". At the end of the table, you need to add a
+cpufreq_freq_table entry with frequency set to CPUFREQ_TABLE_END. And
+if you want to skip one entry in the table, set the frequency to 
+CPUFREQ_ENTRY_INVALID. The entries don't need to be in ascending
+order.
+
+By calling cpufreq_frequency_table_cpuinfo(struct cpufreq_policy *policy,
+					struct cpufreq_frequency_table *table);
+the cpuinfo.min_freq and cpuinfo.max_freq values are detected, and
+policy->min and policy->max are set to the same values. This is
+helpful for the per-CPU initialization stage.
+
+int cpufreq_frequency_table_verify(struct cpufreq_policy *policy,
+                                   struct cpufreq_frequency_table *table);
+assures that at least one valid frequency is within policy->min and
+policy->max, and all other criteria are met. This is helpful for the
+->verify call.
+
+int cpufreq_frequency_table_target(struct cpufreq_policy *policy,
+                                   struct cpufreq_frequency_table *table,
+                                   unsigned int target_freq,
+                                   unsigned int relation,
+                                   unsigned int *index);
+
+is the corresponding frequency table helper for the ->target
+stage. Just pass the values to this function, and the unsigned int
+index returns the number of the frequency table entry which contains
+the frequency the CPU shall be set to. PLEASE NOTE: This is not the
+"index" which is in this cpufreq_table_entry.index, but instead
+cpufreq_table[index]. So, the new frequency is
+cpufreq_table[index].frequency, and the value you stored into the
+frequency table "index" field is
+cpufreq_table[index].index.

+2.1  Performance
+2.2  Powersave
+2.3  Userspace
+
+3.   The Governor Interface in the CPUfreq Core
+
+
+
+1. What Is A CPUFreq Governor?
+==============================
+
+Most cpufreq drivers (in fact, all except one, longrun) or even most
+cpu frequency scaling algorithms only offer the CPU to be set to one
+frequency. In order to offer dynamic frequency scaling, the cpufreq
+core must be able to tell these drivers of a "target frequency". So
+these specific drivers will be transformed to offer a "->target"
+call instead of the existing "->setpolicy" call. For "longrun", all
+stays the same, though.
+
+How to decide what frequency within the CPUfreq policy should be used?
+That's done using "cpufreq governors". Two are already in this patch
+-- they're the already existing "powersave" and "performance" which
+set the frequency statically to the lowest or highest frequency,
+respectively. At least two more such governors will be ready for
+addition in the near future, but likely many more as there are various
+different theories and models about dynamic frequency scaling
+around. Using such a generic interface as cpufreq offers to scaling
+governors, these can be tested extensively, and the best one can be
+selected for each specific use.
+
+Basically, it's the following flow graph:
+
+CPU can be set to switch independetly	 |	   CPU can only be set
+      within specific "limits"		 |       to specific frequencies
+
+                                 "CPUfreq policy"
+		consists of frequency limits (policy->{min,max})
+  		     and CPUfreq governor to be used
+			 /		      \
+			/		       \
+		       /		       the cpufreq governor decides
+		      /			       (dynamically or statically)
+		     /			       what target_freq to set within
+		    /			       the limits of policy->{min,max}
+		   /			            \
+		  /				     \
+	Using the ->setpolicy call,		 Using the ->target call,
+	    the limits and the			  the frequency closest
+	     "policy" is set.			  to target_freq is set.
+						  It is assured that it
+						  is within policy->{min,max}
+
+
+2. Governors In the Linux Kernel
+================================
+
+2.1 Performance
+---------------
+
+The CPUfreq governor "performance" sets the CPU statically to the
+highest frequency within the borders of scaling_min_freq and
+scaling_max_freq.
+
+
+2.1 Powersave
+-------------
+
+The CPUfreq governor "powersave" sets the CPU statically to the
+lowest frequency within the borders of scaling_min_freq and
+scaling_max_freq.
+
+
+2.2 Userspace
+-------------
+
+The CPUfreq governor "userspace" allows the user, or any userspace
+program running with UID "root", to set the CPU to a specifc frequency
+by making a sysfs file "scaling_setspeed" available in the CPU-device
+directory.
+
+
+
+3. The Governor Interface in the CPUfreq Core
+=============================================
+
+A new governor must register itself with the CPUfreq core using
+"cpufreq_register_governor". The struct cpufreq_governor, which has to
+be passed to that function, must contain the following values:
+
+governor->name -	    A unique name for this governor
+governor->governor -	    The governor callback function
+governor->owner	-	    .THIS_MODULE for the governor module (if 
+			    appropriate)
+
+The governor->governor callback is called with the current (or to-be-set)
+cpufreq_policy struct for that CPU, and an unsigned int event. The
+following events are currently defined:
+
+CPUFREQ_GOV_START:   This governor shall start its duty for the CPU
+		     policy->cpu
+CPUFREQ_GOV_STOP:    This governor shall end its duty for the CPU
+		     policy->cpu
+CPUFREQ_GOV_LIMITS:  The limits for CPU policy->cpu have changed to
+		     policy->min and policy->max.
+
+If you need other "events" externally of your driver, _only_ use the
+cpufreq_governor_l(unsigned int cpu, unsigned int event) call to the
+CPUfreq core to ensure proper locking.
+
+
+The CPUfreq governor may call the CPU processor driver using one of
+these two functions:
+
+inline int cpufreq_driver_target(struct cpufreq_policy *policy,
+                                 unsigned int target_freq,
+                                 unsigned int relation);
+
+inline int cpufreq_driver_target_l(struct cpufreq_policy *policy,
+                                   unsigned int target_freq,
+                                   unsigned int relation);
+
+target_freq must be within policy->min and policy->max, of course.
+What's the difference between these two functions? When your governor
+still is in a direct code path of a call to governor->governor, the
+cpufreq_driver_sem lock is still held in the cpufreq core, and there's
+no need to lock it again (in fact, this would cause a deadlock). So
+use cpufreq_driver_target only in these cases. In all other cases (for
+example, when there's a "daemonized" function that wakes up every
+second), use cpufreq_driver_target_l to lock the cpufreq_driver_sem
+before the command is passed to the cpufreq processor driver.

+=========================================
+
+1.1 ARM
+-------
+
+The following ARM processors are supported by cpufreq:
+
+ARM Integrator
+ARM-SA1100
+ARM-SA1110
+
+
+1.2 x86
+-------
+
+The following processors for the x86 architecture are supported by cpufreq:
+
+AMD Elan - SC400, SC410
+AMD mobile K6-2+
+AMD mobile K6-3+
+Cyrix Media GXm
+Intel mobile PIII [*] and Intel mobile PIII-M on certain chipsets
+Intel Pentium 4, Intel Xeon
+National Semiconductors Geode GX
+Transmeta Crusoe
+varios processors on some ACPI 2.0-compatible systems [**]
+
+[*] only certain Intel mobile PIII processors are supported. If you
+know that you own a speedstep-capable processor, pass the option
+"speedstep_coppermine=1" to the module speedstep.o
+
+[**] Only if "ACPI Processor Performance States" are available
+to the ACPI<->BIOS interface.
+
+
+1.3 sparc64
+-----------
+
+The following processors for the sparc64 architecture are supported by
+cpufreq:
+
+UltraSPARC-III
+
+
+
+2. "Policy" / "Governor" ?
+==========================
+
+Some CPU frequency scaling-capable processor switch between varios
+frequencies and operating voltages "on the fly" without any kernel or
+user involvement. This guarantuees very fast switching to a frequency
+which is high enough to serve the user's needs, but low enough to save
+power.
+
+
+2.1 Policy
+----------
+
+On these systems, all you can do is select the lower and upper
+frequency limit as well as whether you want more aggressive
+power-saving or more instantly avaialble processing power.
+
+
+2.2 Governor
+------------
+
+On all other cpufreq implementations, these boundaries still need to
+be set. Then, a "governor" must be selected. Such a "governor" decides
+what speed the processor shall run within the boundaries. One such
+"governor" is the "userspace" governor. This one allows the user - or
+a yet-to-implement userspace program - to decide what specific speed
+the processor shall run at.
+
+
+3. How to change the CPU cpufreq policy and/or speed
+====================================================
+
+3.1 Preferred Interface: sysfs
+------------------------------
+
+The preferred interface is located in the sysfs filesystem. If you
+mounted it at /sys, the cpufreq interface is located in a subdirectory
+"cpufreq" within the cpu-device directory
+(e.g. /sys/devices/sys/cpu0/cpufreq/ for the first CPU).
+
+cpuinfo_min_freq :		this file shows the minimum operating
+				frequency the processor can run at(in kHz) 
+cpuinfo_max_freq :		this file shows the maximum operating
+				frequency the processor can run at(in kHz) 
+scaling_driver :		this file shows what cpufreq driver is
+				used to set the frequency on this CPU
+
+scaling_available_governors :	this file shows the CPUfreq governors
+				available in this kernel. You can see the
+				currently activated governor in
+
+scaling_governor,		and by "echoing" the name of another
+				governor you can change it. Please note
+				that some governors won't load - they only
+				work on some specific architectures or
+				processors.
+scaling_min_freq and 
+scaling_max_freq		show the current "policy limits" (in
+				kHz). By echoing new values into these
+				files, you can change these limits.
+
+
+If you have selected the "userspace" governor which allows you to
+set the CPU operating frequency to a specific value, you can read out
+the current frequency in
+
+scaling_setspeed.		By "echoing" a new frequency into this
+				you can change the speed of the CPU,
+				but only within the limits of
+				scaling_min_freq and scaling_max_freq.
+				
+
+3.2 Deprecated Interfaces
+-------------------------
+
+Depending on your kernel configuration, you might find the following 
+cpufreq-related files:
+/proc/cpufreq
+/proc/sys/cpu/*/speed
+/proc/sys/cpu/*/speed-min
+/proc/sys/cpu/*/speed-max
+
+These are files for deprecated interfaces to cpufreq, which offer far
+less functionality. Because of this, these interfaces aren't described
+here.

+
+1. Supported architectures
+==========================
+
+Some architectures detect the lowest and highest possible speed
+settings, while others rely on user information on this. For the
+latter, a boot parameter is required, for the former, you can specify
+one to set the limits between speed settings may occur. 
+The boot parameter has the following syntax:
+
+     cpufreq=minspeed-maxspeed
+
+with both minspeed and maxspeed being given in kHz. To set the lower
+limit to 59 MHz and the upper limit to 221 MHz, specify:
+
+      cpufreq=59000-221000
+
+Check the "Speed Limits Detection" information below on whether
+the driver detects the lowest and highest allowed speed setting
+automatically.
+
+
+ARM Integrator:
+    SA 1100, SA1110
+--------------------------------
+    Speed Limits Detection: On Integrators, the minimum speed is set
+    and the maximum speed has to be specified using the boot
+    parameter. On SA11x0s, the frequencies are fixed (59 - 287 MHz)
+
+
+AMD Elan:
+    SC400, SC410
+--------------------------------
+    Speed Limits Detection: Not implemented. You need to specify the
+    minimum and maximum frequency in the boot parameter (see above).
+
+
+VIA Cyrix Longhaul:
+    VIA Samuel/CyrixIII, VIA Cyrix Samuel/C3, 
+    VIA Cyrix Ezra, VIA Cyrix Ezra-T
+--------------------------------
+    Speed Limits Detection: working. No need for boot parameters.
+    NOTE: Support for certain processors is currently disabled,
+    waiting on updated docs from VIA.
+
+
+Intel SpeedStep:
+    certain mobile Intel Pentium III (Coppermine), and all mobile
+    Intel Pentium III-M (Tulatin) and mobile Intel Pentium 4 P4-Ms.
+--------------------------------
+    Speed Limits Detection: working. No need for boot parameters.
+    NOTE: 
+    1.) mobile Intel Pentium III (Coppermine):
+        The SpeedStep interface may only be used on SpeedStep
+        capable processors. Unforunately, due to lack of documentation,
+        such detection is not yet possible on mobile Intel PIII
+        (Coppermine) processors. In order to activate SpeedStep on such a
+        processor, you have to remove one line manually in
+        linux/drivers/arch/i386/speedstep.c
+
+
+P4 CPU Clock Modulation:
+    Intel Pentium 4 Xeon processors
+--------------------------------
+    Speed Limits Detection: Not implemented. You need to specify the
+    minimum and maximum frequency in the boot parameter (see above).
+
+
+
+2. User Interface
+=================
+
+CPUFreq uses a "sysctl" interface which is located in 
+	/proc/sys/cpu/0/	  on UP (uniprocessor) kernels, or 
+	/proc/sys/cpu/any/	  on SMP (symmetric multiprocessoring) kernels.
+
+
+In this directory, you will find three files of importance for
+CPUFreq: speed-max, speed-min, and speed: 
+
+speed		    shows the current CPU frequency in kHz, 
+speed-min	    the minimal supported CPU frequency, and
+speed-max	    the maximal supported CPU frequency. 
+
+Please note that you might have to specify these limits as a boot
+parameter depending on the architecture (see above).
+
+
+To change the CPU frequency, "echo" the desired CPU frequency (in kHz)
+to speed. For example, to set the CPU speed to the lowest/highest
+allowed frequency do:
+
+root@notebook:# cat /proc/sys/cpu/0/speed-min > /proc/sys/cpu/0/speed
+root@notebook:# cat /proc/sys/cpu/0/speed-max > /proc/sys/cpu/0/speed
+
+
+2.1   Sample script for command line interface
+**********************************************
+
+
+Michael Ossmann <mike@ossmann.com> has written a small command line
+interface for the infinitely lazy.
+
+#!/bin/bash
+#
+# /usr/local/bin/freq
+#   simple command line interface to cpufreq
+
+[ -n "$1" ] && case "$1" in
+  "min" )
+    # set frequency to minimum
+    cat /proc/sys/cpu/0/speed-min >/proc/sys/cpu/0/speed
+    ;;
+  "max" )
+    # set frequency to maximum
+    cat /proc/sys/cpu/0/speed-max >/proc/sys/cpu/0/speed
+    ;;
+  * )
+    echo "Usage: $0 [min|max]"
+    echo "  min: set frequency to minimum and display new frequency"
+    echo "  max: set frequency to maximum and display new frequency"
+    echo "  no options: display current frequency"
+    exit 1
+    ;;
+esac
+
+# display current frequency
+cat /proc/sys/cpu/0/speed
+exit 0
+
+
+
+3.  CPUFreq core and interfaces
+===============================
+
+3.1   General information
+*************************
+
+The CPUFreq core code is located in linux/kernel/cpufreq.c. This
+cpufreq code offers a standardized interface for the CPUFreq
+architecture drivers (those pieces of code that do the actual
+frequency transition), as well as to "notifiers". These are device
+drivers or other part of the kernel that need to be informed of
+frequency changes (like timing code) or even need to force certain
+speed limits (like LCD drivers on ARM architecture). Aditionally, the
+kernel "constant" loops_per_jiffy is updated on frequency changes
+here.
+
+
+3.2   CPUFreq notifiers
+***********************
+
+CPUFreq notifiers are kernel code that need to be called to either
+a) define certain minimum or maximum speed settings,
+b) be informed of frequency changes in advance of the transition, or
+c) be informed of frequency changes directly after the transition.
+
+A standard kernel notifier interface is offered for this. See
+linux/include/linux/notifier.h for details on notifiers.
+
+
+Data and value passed to CPUFreq notifiers
+------------------------------------------
+The second argument passed to any notifier is an unsigned int stating
+the phase of the transition: 
+CPUFREQ_MINMAX during the process of determing a valid new CPU
+	       frequency,
+CPUFREQ_PRECHANGE right before the transition, and 
+CPUFREQ_POSTCHANGE right after the transition.
+
+The third argument, a void *pointer, points to a struct
+cpufreq_freqs. This consists of four values: min, max, cur and new.
+
+min and max are the current speed limits. Please note: Never update
+these values directly, use cpufreq_updateminmax(struct cpufreq_freqs
+*freqs, unsigned int min, unsigned int max) instead. cur is the
+current/old speed, and new is the new speed, but might only be valid
+on CPUFREQ_PRECHANGE or CPUFREQ_POSTCHANGE.
+
+Each notifier gets called all three times on any transition:
+
+CPUFREQ_MINMAX
+Here the notifier is supposed to update the min and max values to the
+limits the protected device / kernel code needs. As stated above,
+always use cpufreq_updateminmax for this.
+
+CPUFREQ_PRECHANGE
+CPUFREQ_POSTCHANGE
+Here the notifier is supposed to update all internal (e.g. device
+driver) code which is dependend on the CPU frequency.
+
+
+3.3   CPUFreq architecture drivers
+**********************************
+
+CPUFreq architecture drivers are the pieces of kernel code that
+actually perform CPU frequency transitions. These need to be
+initialised seperately (seperate initcalls), and may be
+modularized. They interact with the CPUFreq core in the following way:
+
+
+cpufreq_register()
+------------------
+cpufreq_register registers an arch driver to the CPUFreq core. Please
+note that only one arch driver may be registered at any time, -EBUSY
+is returned when an arch driver is already registered. The argument to
+cpufreq_register, cpufreq_driver_t driver, is described later.
+
+
+cpufreq_unregister()
+--------------------
+cpufreq_unregister unregisters an arch driver, e.g. on module
+unloading. Please note that there is no check done that this is called
+from the driver which actually registered itself to the core, so
+please only call this function when you are sure the arch driver got
+registered correctly before.
+
+
+struct cpufreq_driver
+----------------
+On initialisation, the arch driver is supposed to pass the following
+entries in struct cpufreq_driver cpufreq_driver:
+
+cpufreq_verify_t validate: This is a pointer to a function with the
+following definition: 
+     unsigned int validating_function (unsigned int kHz). 
+It is called right before a transition occurs. The proposed new
+speed setting is passed as an argument in kHz; the validating code
+should verify this is a valid speed setting which is currently
+supported by the CPU. It shall return the closest valid CPU frequency
+in kHz.
+
+cpufreq_setspeed_t setspeed: This is a pointer to a function with the
+following definition: 
+     void setspeed_function (unsigned int kHz). 
+This function shall perform the transition to the new CPU frequency 
+given as argument in kHz. Note that this argument is exactly the same
+as the one returned by cpufreq_verify_t validate.
+
+
+unsigned int freq.cur: The current CPU core frequency. Note that this
+is a requirement while the next two entries are optional.
+
+
+unsigned int freq.min (optional): The minimal CPU core frequency this
+CPU supports. This value may be limited further by the
+cpufreq_verify_t validate function, and so this value should be the
+minimal core frequency allowed "theoretically" on this system in this
+configuration.
+
+
+unsigned int freq.max (optional): The maximum CPU core frequency this
+CPU supports. This value may be limited further by the
+cpufreq_verify_t validate function, and so this value should be the
+maximum core frequency allowed "theoretically" on this system in this
+configuration.
+
+
+Some Requirements to CPUFreq architecture drivers
+-------------------------------------------------
+* Only call cpufreq_register() when the ability to switch CPU
+  frequencies is _verified_ or can't be missing
+* cpufreq_unregister() may only be called if cpufreq_register() has
+  been successfully(!) called before
+* All CPUs have to be set to the same speed whenever setspeed() is
+  called
+* Be aware that there is currently no error management in the
+  setspeed() code in the CPUFreq core. So only call yourself a
+  cpufreq_driver if you are really a working cpufreq_driver!
+

+			Low Level Serial API
+			--------------------
+
+
+   $Id: driver,v 1.3 2001/11/24 23:24:47 rmk Exp $
+
+
+This document is meant as a brief overview of some aspects of the new serial
+driver.  It is not complete, any questions you have should be directed to
+<rmk@arm.linux.org.uk>
+
+The reference implementation is contained within serial_amba.c.
+
+
+
+Low Level Serial Hardware Driver
+--------------------------------
+
+The low level serial hardware driver is responsible for supplying port
+information (defined by uart_port) and a set of control methods (defined
+by uart_ops) to the core serial driver.  The low level driver is also
+responsible for handling interrupts for the port, and providing any
+console support.
+
+
+Console Support
+---------------
+
+The serial core provides a few helper functions.  This includes identifing
+the correct port structure (via uart_get_console) and decoding command line
+arguments (uart_parse_options).
+
+
+Locking
+-------
+
+Generally, all locking is done by the core driver, except for the interrupt
+functions.  It is the responsibility of the low level hardware driver to
+perform the necessary locking there using info->lock. (since it is running
+in an interrupt, you only need to use spin_lock() and spin_unlock() from
+the interrupt handler).
+
+
+uart_ops
+--------
+
+The uart_ops structure is the main interface between serial_core and the
+hardware specific driver.  It contains all the methods to control the
+hardware.
+
+  tx_empty(port)
+	This function tests whether the transmitter fifo and shifter
+	for the port described by 'port' is empty.  If it is empty,
+	this function should return TIOCSER_TEMT, otherwise return 0.
+	If the port does not support this operation, then it should
+	return TIOCSER_TEMT.
+
+  set_mctrl(port, mctrl)
+	This function sets the modem control lines for port described
+	by 'port' to the state described by mctrl.  The relevant bits
+	of mctrl are:
+		- TIOCM_RTS	RTS signal.
+		- TIOCM_DTR	DTR signal.
+		- TIOCM_OUT1	OUT1 signal.
+		- TIOCM_OUT2	OUT2 signal.
+	If the appropriate bit is set, the signal should be driven
+	active.  If the bit is clear, the signal should be driven
+	inactive.
+
+  get_mctrl(port)
+	Returns the current state of modem control inputs.  The state
+	of the outputs should not be returned, since the core keeps
+	track of their state.  The state information should include:
+		- TIOCM_DCD	state of DCD signal
+		- TIOCM_CTS	state of CTS signal
+		- TIOCM_DSR	state of DSR signal
+		- TIOCM_RI	state of RI signal
+	The bit is set if the signal is currently driven active.  If
+	the port does not support CTS, DCD or DSR, the driver should
+	indicate that the signal is permanently active.  If RI is
+	not available, the signal should not be indicated as active.
+
+  stop_tx(port,from_tty)
+	Stop transmitting characters.  This might be due to the CTS
+	line becoming inactive or the tty layer indicating we want
+	to stop transmission.
+
+  start_tx(port,nonempty,from_tty)
+	start transmitting characters.  (incidentally, nonempty will
+	always be nonzero, and shouldn't be used - it will be dropped).
+
+  stop_rx(port)
+	Stop receiving characters; the port is in the process of
+	being closed.
+
+  enable_ms(port)
+	Enable the modem status interrupts.
+
+  break_ctl(port,ctl)
+	Control the transmission of a break signal.  If ctl is
+	nonzero, the break signal should be transmitted.  The signal
+	should be terminated when another call is made with a zero
+	ctl.
+
+  startup(port,info)
+	Grab any interrupt resources and initialise any low level driver
+	state.  Enable the port for reception.  It should not activate
+	RTS nor DTR; this will be done via a separate call to set_mctrl.
+
+  shutdown(port,info)
+	Disable the port, disable any break condition that may be in
+	effect, and free any interrupt resources.  It should not disable
+	RTS nor DTR; this will have already been done via a separate
+	call to set_mctrl.
+
+  change_speed(port,cflag,iflag,quot)
+	Change the port parameters, including word length, parity, stop
+	bits.  Update read_status_mask and ignore_status_mask to indicate
+	the types of events we are interested in receiving.  Relevant
+	cflag bits are:
+		CSIZE	- word size
+		CSTOPB	- 2 stop bits
+		PARENB	- parity enable
+		PARODD	- odd parity (when PARENB is in force)
+		CREAD	- enable reception of characters (if not set,
+			  still receive characters from the port, but
+			  throw them away.
+		CRTSCTS	- if set, enable CTS status change reporting
+		CLOCAL	- if not set, enable modem status change
+			  reporting.
+	Relevant iflag bits are:
+		INPCK	- enable frame and parity error events to be
+			  passed to the TTY layer.
+		BRKINT
+		PARMRK	- both of these enable break events to be
+			  passed to the TTY layer.
+
+		IGNPAR	- ignore parity and framing errors
+		IGNBRK	- ignore break errors,  If IGNPAR is also
+			  set, ignore overrun errors as well.
+	The interaction of the iflag bits is as follows (parity error
+	given as an example):
+	Parity error	INPCK	IGNPAR
+	None		n/a	n/a	character received
+	Yes		n/a	0	character discarded
+	Yes		0	1	character received, marked as
+					TTY_NORMAL
+	Yes		1	1	character received, marked as
+					TTY_PARITY
+
+  pm(port,state,oldstate)
+	perform any power management related activities on the specified
+	port.  state indicates the new state (defined by ACPI D0-D3),
+	oldstate indicates the previous state.  Essentially, D0 means
+	fully on, D3 means powered down.
+
+	This function should not be used to grab any resources.
+
+  type(port)
+	Return a pointer to a string constant describing the specified
+	port, or return NULL, in which case the string 'unknown' is
+	substituted.
+
+  release_port(port)
+	Release any memory and IO region resources currently in use by
+	the port.
+
+  request_port(port)
+	Request any memory and IO region resources required by the port.
+	If any fail, no resources should be registered when this function
+	returns, and it should return -EBUSY on failure.
+
+  config_port(port,type)
+	Perform any autoconfiguration steps required for the port.  `type`
+	contains a bit mask of the required configuration.  UART_CONFIG_TYPE
+	indicates that the port requires detection and identification.
+	port->type should be set to the type found, or PORT_UNKNOWN if
+	no port was detected.
+
+	UART_CONFIG_IRQ indicates autoconfiguration of the interrupt signal,
+	which should be probed using standard kernel autoprobing techniques.
+	This is not necessary on platforms where ports have interrupts
+	internally hard wired (eg, system on a chip implementations).
+
+  verify_port(port,serinfo)
+	Verify the new serial port information contained within serinfo is
+	suitable for this port type.
+
+  ioctl(port,cmd,arg)
+	Perform any port specific IOCTLs.  IOCTL commands must be defined
+	using the standard numbering system found in <asm/ioctl.h>
+
+
+Other notes
+-----------
+
+It is intended some day to drop the 'unused' entries from uart_port, and
+allow low level drivers to register their own individual uart_port's with
+the core.  This will allow drivers to use uart_port as a pointer to a
+structure containing both the uart_port entry with their own extensions,
+thus:
+
+	struct my_port {
+		struct uart_port	port;
+		int			my_stuff;
+	};

+The FP structure has 4 words reserved for each register, the first is used just
+for the sign in bit 31, the second and third are for the mantissa (unsigned
+integer, high 32 bit first) and the fourth is the exponent (signed integer).
+The mantissa is always normalized.
+
+If the exponent is 0x80000000, that is the most negative value, the number
+represented is 0 and both mantissa words are also 0.
+
+If the exponent is 0x7fffffff, that is the biggest positive value, the number
+represented is infinity if the high 32 mantissa bit are also 0, otherwise it is
+a NaN. The low 32 mantissa bit are 0 if the number represented is infinity.
+
+Decimal and packed decimal numbers are not supported yet.
+
+The parameters to these functions are r0=destination pointer, r1 and r2
+source pointers. r4 is the instruction. They may use r0-r8 and r14. They return
+to fastfpe_next, except CPDO_rnf_core which expects the return address in r14.

+ *  Miscellaneous character device interface for SA1100 USB function
+ *	driver.
+ *
+ *  Background:
+ *  The SA1100 function driver ported from the Compaq Itsy project
+ *  has an interface, usb-eth.c, to feed network packets over the
+ *  usb wire and into the Linux TCP/IP stack.
+ *
+ *  This file replaces that one with a simple character device
+ *  interface that allows unstructured "byte pipe" style reads and
+ *  writes over the USB bulk endpoints by userspace programs.
+ *
+ *  A new define, CONFIG_SA1100_USB_NETLINK, has been created that,
+ *  when set, (the default) causes the ethernet interface to be used.
+ *  When not set, this more pedestrian character interface is linked
+ *  in instead.
+ *
+ *  Please see linux/Documentation/arm/SA1100/SA1100_USB for details.
+ *
+ *  ward.willats@extenex.com
+ *
+ *  To do:
+ *  - Can't dma into ring buffer directly with pci_map/unmap usb_recv
+ *    uses and get bytes out at the same time DMA is going on. Investigate:
+ *    a) changing usb_recv to use alloc_consistent() at client request; or
+ *    b) non-ring-buffer based data structures. In the meantime, I am using
+ *    a bounce buffer. Simple, but wasteful.

+ * A summary of three types of data-returning setups:

+ * 1. Setup request <= 8 bytes. That is, requests that can

+ *    with IPR in queue_and_start_write(). (I don't know
+ *    if there really are any of these!)
+ *
+ * 2. Setup requests > 8 bytes (requiring more than one
+ *    IN to get back to the host), and we have at least
+ *    as much or more data than the host requested. In
+ *    this case we pump out everything we've got, and
+ *    when the final interrupt comes in due to the UDC
+ *    clearing the last IPR, we just set DE.
+ *
+ * 3. Setup requests > 8 bytes, but we don't have enough
+ *    data to satisfy the request. In this case, we send
+ *    everything we've got, and when the final interrupt
+ *    comes in due to the UDC clearing the last IPR
+ *    we write nothing to the FIFO and set both IPR and DE
+ *    so the UDC sends an empty packet and forces the host
+ *    to perform short packet retirement instead of stalling
+ *    out.

+ *
+ * Hardware: 
+ *
+ * matrix scan keyboards based on EP7209,7211,7212,7312 and CS89712 
+ * on chip keyboard scanner.		
+ * Adaption for different machines is done in init function.
+ *
+ * Basic Function:
+ *
+ * Basicly the driver is interrupt driven. It sets all column drivers	
+ * high. If any key is pressed, a interrupt occures. Now a seperate scan of
+ * each column is done. This scan is timer based, because we use a keyboard 
+ * interface with decoupling capacitors (neccecary if you want to survive 
+ * EMC compliance tests). Always one line is set high. When next timer event 
+ * occures the scan data on port A are valid. This makes also sure, that no
+ * spurious keys are scanned. The kbd int on these CPU's is not deglitched!
+ * After scanning all columns, we switch back to int mode, if no key is
+ * pressed. If any is pressed we reschedule the scan within a programmable
+ * delay. If we would switch back to interrupt mode as long as a key is pressed,
+ * we come right back to the interrupt, because the int. is level triggered !
+ * The timer based scan of the seperate columns can also be done in one
+ * timer event (set fastscan to 1).
+ *
+ * Summary:
+ * The design of this keyboard controller chip is stupid at all !
+ *
+ * Matrix translation:
+ * The matrix translation table is based on standard XT scancodes. Maybe
+ * you have to adjust the KEYISPRINTABLE macro if you set other codes.
+ *
+ * HandyKey:
+ *
+ * On small matrix keyboards you don't have enough keys for operation.
+ * The intention was to implement a operation mode as it's used on handys.
+ * You can rotate trough four scancode levels and produce e.g. with a 4x3
+ * matrix 4*3*4 = 48 different keycodes. That's basicly enough for editing
+ * filenames or things like that. The HandyKey function takes care about 
+ * nonprintable keys like cursors, backspace, del ...
+ * If a key is pressed and is a printable keycode, the code is put to the
+ * main keyboard handler and a cursor left is applied. If you press the same
+ * key again, the current character is deleted and the next level character
+ * is applied. (e.g. 1, a, b, c, 1 ....). If you press a different key, the
+ * driver applies cursor right, before processing the new key.
+ * The autocomplete feature moves the cursor right, if you do not press a
+ * key within a programmable time.
+ * If HandyKey is off, the keyboard behaviour is that of a standard keyboard
+ * HandyKey can be en/disabled from userspace with the proc/keyboard entry
+ * 
+ * proc/keyboard:
+ * 
+ * Read access gives back the actual state of the HandyKey function	
+ *	h:0	Disabled
+ *	h:1	Enabled
+ * Write access has two functions. Changing the HandyKey mode and applying
+ * a different scancode translation table.
+ * Syntax is: 	h:0	disable Handykey
+ *		h:1	enabled Handykey
+ *		t:array[256] of bytes	Transfer translation table

+ * SA1111 PS/2 keyboard/mouse driver
+ *
+ * 2000 by VASARA RESEARCH INC.
+ *
+ * Changelog:
+ *     Jun.xx,2000:    Kunihiko IMAI <imai@vasara.co.jp>
+ *                     Port to 2.4.0test1-ac19-rmk1-np1
+ *     Apr.17,2000:    Takafumi Kawana <kawana@pro.or.jp>
+ *                     Internal Release for XP860
+ *
+ *
+ * This driver is based on linux/drivers/char/pc_keyb.c
+ * Original declaration follows:
+
+ *
+ * linux/drivers/char/pc_keyb.c
+ *
+ * Separation of the PC low-level part by Geert Uytterhoeven, May 1997
+ * See keyboard.c for the whole history.
+ *
+ * Major cleanup by Martin Mares, May 1997
+ *
+ * Combined the keyboard and PS/2 mouse handling into one file,
+ * because they share the same hardware.
+ * Johan Myreen <jem@iki.fi> 1998-10-08.
+ *
+ * Code fixes to handle mouse ACKs properly.
+ * C. Scott Ananian <cananian@alumni.princeton.edu> 1999-01-29.

- * This is a generic driver for ARM AMBA-type serial ports.  They
- * have a lot of 16550-like features, but are not register compatable.
- * Note that although they do have CTS, DCD and DSR inputs, they do
- * not have an RI input, nor do they have DTR or RTS outputs.  If
- * required, these have to be supplied via some other means (eg, GPIO)
- * and hooked into this driver.
- *
- * This could very easily become a generic serial driver for dumb UARTs
- * (eg, {82,16x}50, 21285, SA1100).

+/*
+ * CyberPro 2000 video capture driver for the Rebel.com NetWinder
+ *
+ * (C) 1999-2000 Russell King
+ *
+ *  Re-written from Rebel.com's vidcap driver.
+ *
+ * Architecture
+ * ------------
+ *  The NetWinder video capture consists of a SAA7111 video decoder chip
+ *  connected to the CyberPro feature bus.  The video data is captured to
+ *  the VGA memory, where the CyberPro can overlay (by chromakeying) the
+ *  data onto the VGA display.
+ *
+ *  The CyberPro also has some nifty features, including a second overlay
+ *  and picture in picture mode.  We do not currently use these features.
+ *
+ * Power Saving
+ * ------------
+ *  Please note that rev.5 NetWinders have the ability to hold the SAA7111
+ *  decoder chip into reset, which saves power.  The only time at which
+ *  this is done is when the driver is unloaded, which implies that this
+ *  is compiled as a module.
+ *
+ *  In this case, you will want the kernel to automatically load this
+ *  driver when required.  Place the following line in /etc/modules.conf
+ *  to enable this:
+ *
+ *   alias char-major-81-0 cyberpro
+ *
+ *  The relevant modules will be automatically loaded by modprobe on a
+ *  as and when needed basis.
+ *
+ * Capture resolution
+ * ------------------
+ *  The maximum useful capture resolution is:
+ *     625-line UK: 716x576
+ *     525-line US: ?
+ *
+ * Bugs
+ * ----
+ *  1. The CyberPro chip seems to be prone to randomly scribbling over VGA
+ *     memory [hopefully fixed with new capture enable/freeze stuff]
+ *  2. read()ing pauses video capture, and sometimes triggers bug 1.
+ *  3. mmap() is not supported (requires BM-DMA - see bug 4)
+ *  4. Really, we want to do scatter BM-DMA.  Is the CyberPro capable of this?
+ *     The Cyberpro seems to randomly scribble to various PCI addresses if you
+ *     transfer >16 words.
+ *  5. We shouldn't ignore O_NONBLOCK when reading a frame.
+ *  6. The incoming stream on the NetWinder is CCIR656, which is YUV422.
+ *     CyberPro docs also call the format we capture and overlay "YUV422",
+ *     but we actually seem to have Y, U, Y, V bytes (is this YUYV format?)

+ *
+ *
+ * History:
+ *
+ * 2000-05-21	Nicolas Pitre	Initial release.
+ *
+ * 2000-06-10	Erik Bunce	Add initial poll support.
+ *
+ * 2000-08-22	Nicolas Pitre	Removed all DMA stuff. Now using the
+ * 				generic SA1100 DMA interface.
+ *
+ * 2000-11-30	Nicolas Pitre	- Validation of opened instances;
+ * 				- Power handling at open/release time instead
+ * 				  of driver load/unload;
+ *
+ * 2001-06-03	Nicolas Pitre	Made this file a separate module, based on
+ * 				the former sa1100-uda1341.c driver.
+ *
+ * 2001-07-22	Nicolas Pitre	- added mmap() and realtime support
+ * 				- corrected many details to better comply
+ * 				  with the OSS API
+ *
+ * 2001-10-19	Nicolas Pitre	- brought DMA registration processing
+ * 				  into this module for better ressource
+ * 				  management.  This also fixes a bug
+ * 				  with the suspend/resume logic.

+This directory holds the SSI bus drivers.  Basically, a SSI bus consists
+of the following signals:
+
+	stxd	Transmit data
+	srxd	Receive data
+	sclk	Clock
+	sfrm	Frame
+		Chip selects (1 - n)
+
+There may be more than one device on a SSI bus, and each device can
+have different timing requirements.  There are several frame formats:
+
+1. Texas Instruments Synchronous Serial Frame format
+
+   sclk ____~_~_~_~_~_~_~_~____
+   sfrm ____~~_________________
+   stxd ------bn..........b0---
+   srxd ------bn..........b0---
+
+   - data latched in on the falling edge of the clock
+   - data shifted out on the rising edge of the clock
+
+2. Motorola SPI frame format
+
+   sclk ______~_~_~_~_~_~_~____
+   sfrm ~~~~________________~~~
+   stxd -----bn..........b0----
+   srxd ----.bn..........b0----
+
+   - data latched in on the rising edge of the clock
+   - data shifted out on the falling edge of the clock, or falling edge
+     of sfrm
+
+3. National Microwire format
+
+   sclk ______~_~_~_~_~_~_~_~_~_~_~_~_~_____
+   sfrm ~~~~_____________________________~~~
+   stxd -----bn......b0---------------------
+   srxd -----------------bn..........b0.----
+
+   - data latched in on the rising edge of the clock
+   - data shifted out on the falling edge of the clock
+   - half duplex, one clock between transmission and reception
+
+Types of devices
+----------------
+
+The following types of devices can be found on a SSP bus:
+
+	Sound chips
+	Keyboard devices
+	Touch screen devices
+
+Keyboard
+--------
+
+TX:
+0. Format: cfglen = 8, framelen = 8, clkpol = 1, clk < 250kHz
+1. select device
+2. keyboard responds asserting key_atn
+3. wait 0.1ms to 5ms
+4. transmit data byte
+5. wait >= 150us
+6. repeat step 4 until all data sent
+7. deselect device
+8. keyboard responds de-asserting key_atn
+9. wait >= 120us
+
+RX:
+0. Format: cfglen = 8, framelen = 8, clkpol = 1, clk < 250kHz
+1. keyboard asserts key_atn
+2. select device after 0.1ms < 5ms
+3. read data byte
+4. wait 150us
+5. if key_atn still asserted, goto 3
+6. deselect device
+7. wait >= 120us
