They provided support based on 2.4.21-rmk1 ++kernels, and they said that there might be 2.6.x support some day. ++Meanwhile they've released a 2.6.8.1 based kernel called "ursus". ++ ++Currently we still have got a communication problem with cirrus, ++for some reason it seems to be impossible to directly talk to their ++developers. Hope this will change some day, but we really cannot afford ++to just sit down and wait. ++ ++The purpose of this file is to document success and todo's. ++ ++ - Section II describes hardware support, organized according to the ++ EP9315 datasheet. Other device datasheets are ordered similarly, ++ though section numbers may vary. ++ ++ - Section III contains other miscellaneous information. ++ ++The latest version of this document may be found at: ++ ++ linux/Documentation/arm/ep93xx/status.txt ++ ++projects homepage can be found at: ++ ++ http://members.inode.at/m.burian/ep93xx/index.html ++ ++ ++====================================================================== ++(II) Hardware Support ++====================================================================== ++ ++These section numbers mirror the EP9315 datasheet. ++ ++1. Introduction ++--------------- ++N/A ++ ++2. ARM920T Core and Advanced High-Speed Bus (AHB) ++------------------------------------------------- ++We have standard Linux 2.6 support for ARM920T Core. Thumb support ++is pretty shaky, as most people do not seem to use Thumb in the ++kernel. Address translation uses 16K small pages exclusively (FIXME: ++is this true?) ++ ++3. MaverickCrunch Coprocessor ++----------------------------- ++People have started with forward porting. Note that there's more ++to it than just kernel support. You also need to have a toolchain ++supporting it. We're in need of a comprehensive HOWTO that explains kernel, ++toolchain and userspace aspects to a point where average developers can use it ++ ++ ++4. Boot ROM ++----------- ++Well, not really kernel related, most people start with redboot. Make ++sure to use a version that passes the correct machine type. Some ++people also started porting blob / uboot. ++ ++If any support is added for this device, it will likely be a simple ++char device that allows you to read the contents of the boot rom ++for interests sake. ++ ++5. System Controller ++-------------------- ++System Controllers registers are set by startup code and by individual ++drivers as needed, we try to keep the processor dependent stuff to ++a minimum. ++ ++Ray really wants to overhaul the system configuration stuff and move ++towards something like the SA1100 people are doing. It should make ++things a lot cleaner for drivers that share physical pins, or for ++multifunctional blocks that require several drivers (eg: UART2 with ++IrDA support) ++ ++There is currently no dynamic clock control support. We'll probably ++want to tie into the CPUfreq code at some point. ++ ++There is no support for querying the system boot configuration or ++last reset source. ++ ++There is no power management support. Individual drivers may power ++up silicon blocks as required. Some research is needed to map the ++EP93xx power states onto the ACPI or PCI states that everyone seems ++to use. ++ ++There is no support for the TICK and WATCHDOGEXPIRED interrupts ++generated by this block. ++ ++There is no support for the AHB bus arbiter priority settings. ++ ++6. Vectored Interrupt Controller ++-------------------------------- ++Since we can boot this can't be done dead wrong. Standard level-triggered ++interrupt support is present. ++ ++No FIQ interrupts are supported. ++ ++Support for demultiplexing GPIO IRQs is available. ++ ++ ++7. Raster Engine With Analog/LCD Integrated Timing and Interface ++---------------------------------------------------------------- ++ ++Michael has rewritten large parts of the framebuffer driver based on ++skeleton.c. You need to adapt this in case you can't live with ++the standard display(s) that are included. Framebuffer is fixed ++size, you can change some settings at compile time, though. ++TODO: clean ups, different resolutions, etc ++ ++ ++8. Graphics Accelerator ++----------------------- ++not available yet, will be done after the framebuffer code has been ++cleaned up. ++ ++ ++9. 1/10/100 Mbps Ethernet LAN Controller ++---------------------------------------- ++Supported. Driver has been reviewed and cleaned up. ++Uses generic mii routines now. It might be possible ++to use DMA - but in that case we'd need to find a ++workaround to get around the fact that it can only ++transfer 32bit aligned data, while we'd need to transfer ++data that's only 16 bit aligned. ++ ++NICE-TO-HAVE: Could be ported to use NAPI. ++ ++10. DMA Controller ++------------------ ++There is some code and documentation ported forward from the Cirrus ++2.4 port. ++ ++11. Universal Serial Bus Host Controller ++---------------------------------------- ++Ray has written some glue code to plug the OHCI host controller into ++the Linux 2.6 USB stack. This has been tested on an EDB9301 board with ++a single port populated. A serial dongle worked fine, and several ++different flash keys seem to work okay with the USB mass storage ++driver using SCSI disk emulation. This hasn't really been stress tested ++yet, but initial results look very encouraging. ++ ++12. Static Memory Controller ++---------------------------- ++Not sure how much kernel support is required here. Flash and memory ++timing needs to be setup by the bootloader, so there's not much ++that needs to be done here. ++ ++No support for PCMCIA at this time. ++ ++13. SDRAM, SyncROM, and SyncFLASH Controller ++-------------------------------------------- ++Again, this is probably the bootloaders problem. ++ ++There is an errata about system instability when suspending with ++an SDRAM bus speed over 50 MHz. May need to tweak this if we start ++doing power management modes. ++ ++14. UART1 With HDLC and Modem Control Signals ++--------------------------------------------- ++We've got a driver to use this one as UART. No DMA support. FIFO support ++works. No HDLC support. Needs some syscon support to cleanly handle ++HDLC and some modem signals. ++ ++15. UART2 ++--------- ++We've got a driver to use this one as UART. No DMA support. FIFO support ++works. No IrDA SIR support. Needs some syscon support to cleanly handle ++IrDA SIR. ++ ++16. UART3 With HDLC Encoder ++--------------------------- ++We've got a driver to use this one as UART. No DMA support. FIFO support ++works. No HDLC or RS-485 support. Needs some syscon support to cleanly ++handle HDLC and RS-485. ++ ++17. IRDA ++-------- ++There is some code and documentation ported forward from the Cirrus ++2.4 port. No idea how well this works, if at all. ++ ++18. TIMERS ++---------- ++Timer1 is used at 508 kHz with a reload value of 5080 to provide a 100 Hz ++tick signal to drive the kernel. ++ ++Timer 2 and 3 are not currently used, nor is the debug timer 4. ++ ++ ++19. WATCHDOG Timer ++------------------ ++Ray has some initial experimental code written (not pushed) to drive this. ++The onboard watchdog seems to have a 250 ms (!) timeout, while most PC ++dogs seem to have timeouts on the order of one minute or more. The standard ++approach of having a user level process open the watchdog device and ++kick it every so often seems like a bad idea here... a momentary system ++load spike could easily delay the monitor from being scheduled, and the ++system would reboot. ++ ++Test out a watchdog monitor running at a high scheduling priority, or else ++design a kernel watchdog that kicks the dog every timer tick and exports ++a more reasonable timeout value to userspace. ++ ++20. Real Time Clock With Software Trim ++-------------------------------------- ++We did not bother to write a driver yet, it would require a design ++that ensures CPU is always powered on, and always have at least ++a 32kHz clock running. Most people prefer to use and external RTC. ++We've got support for the DS1337 RTC that seems to be popular on ++ep93xx based boards. ++ ++21. I2S Controller ++------------------ ++No support yet. Klaus is working on it. ++ ++22. AC97 Controller ++------------------- ++Supported but could need some testing. ++ ++23. Synchronous Serial Port ++--------------------------- ++Two driver are available, a forward port from the cirrus driver and ++another driver from Ray. ++ ++24. Pulse Width Modulator ++------------------------- ++No support yet. ++ ++25. Analog Touch Screen Interface ++--------------------------------- ++People already played with this, AFAIK one would need a silicon ++revision > D1 (November 2004) for this to work properly. ++ ++26. Keypad Interface ++-------------------- ++We've got a driver for the 8x8 keypad. Chances are that you might ++want to create a custom keymap. There's also support for mobile ++phone like input (key 1 becomes -> A -> B -> C) if pressed repeatedly ++within half a second. ++ ++27. IDE interface ++----------------- ++We've got IDE working in polling only, no DMA support so far. ++It needs to be cleaned up, too. ++ ++28. GPIO ++-------- ++Standard LED support for red and green leds is present. ++ ++Michael has written an I2C bus driver using the new Linux device driver model. ++It supports an external DS1337 RTC device on the EECLK/EEDAT pins. ++ ++Need some syscon support to cleanly handle the multi-function GPIO pins. ++ ++Demultiplexing of GPIO interrupts is possible now. ++ ++29. Security ++------------ ++No information available on this, so support is unlikely in the near future. ++ ++30.

These machines are embedded systems and this keyboard driver ++ * can support small keyboards. ++ * ++ * The keyboard driver does not have a normal device driver interface ++ * and instead interfaces to the keyboard.c driver through function calls. ++ * Note that not all interface function calls are implemented at this time. ++ * (see /asm/arch/keyboard.h for function definitions): ++ * ++ * ep93xxkbd_init ++ * initializes the scan keyboard hw. ++ * ++ * handle_scancode ++ * when scan controller generates interrupt, handler ++ * used to pass scan codes to queue in keyboard.c with this function call. ++ * ++ * UPDATE: Now this is inplemented right here and just used as a ++ * wrapper for the input layer ++ * ++ * Note that key scan codes will be delivered by this driver on both ++ * key down and key up events, using a coding similar to PC XT keyboard. ++ * ++ * Note however that scan compatibility and key code compatibility ++ * to PC standard are not required by Linux, and are not guaranteed. ++ * ++ ******************************************************************************/ ++#include <linux/config.h> ++#include <linux/kernel.h> ++#include <linux/module.h> ++#include <linux/sched.h> ++#include <linux/interrupt.h> ++#include <linux/input.h> ++#include <linux/init.h> ++#include <asm/io.h> ++#include <asm/uaccess.h> ++#include <asm/arch/keyboard.h> ++#include <asm/hardware.h> ++ ++#ifdef CONFIG_KEYBOARD_EP93XX_8X8_CYCLING ++#include "ep93xx_kbd_8x8_keymap-cycling.h" ++#else ++#include "ep93xx_kbd_8x8_keymap.h" ++#endif ++ ++#define EP93XX_KEYMAP_SIZE (8*8) ++ ++/* #define DEBUG */ ++ ++#define KEYREG_KEY1_MASK 0x0000003F ++#define KEYREG_KEY1_SHIFT 0 ++#define KEYREG_KEY2_MASK 0x00000Fc0 ++#define KEYREG_KEY2_SHIFT 6 ++ ++#define KEYREG_KEY1ROW_MASK 0x00000007 ++#define KEYREG_KEY1ROW_SHIFT 0 ++#define KEYREG_KEY1COL_MASK 0x00000038 ++#define KEYREG_KEY1COL_SHIFT 3 ++ ++#define KEYREG_KEY2ROW_MASK 0x000001c0 ++#define KEYREG_KEY2ROW_SHIFT 6 ++#define KEYREG_KEY2COL_MASK 0x00000E00 ++#define KEYREG_KEY2COL_SHIFT 9 ++ ++#define KEYREG_1KEY 0x00001000 ++#define KEYREG_2KEYS 0x00002000 ++#define KEYREG_INT 0x00004000 ++#define KEYREG_K 0x00008000 ++ ++#define SCANINIT_DIS3KY 0x00008000 ++ ++static struct input_dev *dev; ++ ++#ifdef CONFIG_KEYBOARD_EP93XX_8X8_CYCLING ++struct last_key_event { ++ unsigned long jiffies; ++ unsigned char scancode; ++}; ++ ++static struct last_key_event lke; ++ ++/** ++ * handle_scancode - wrapper ++ * ++ * We need to do two things here: ++ * 1. wrap old style (2.4.x) to 2.6.x input subsystem ++ * 2. also implement the key cycling feature here. ++ * CYCLING FEATURE: ++ * If the same key is pressed withing 500ms, we send a delete ++ * character to delete the former key, and use the keycode from the next layer ++ * instead.
