Previous support for these + "cansleep" calls was just stubs. (One example: the widely used + pcf8574 I2C chips, with 8 GPIOs each.) + + * Including a non-stub implementation of the gpio_{request,free}() calls, + making those calls much more useful.

That will list all the controllers registered through ++this framework, and the state of the GPIOs currently in use. ++ ++ ++Controller Drivers: gpio_chip ++----------------------------- ++In this framework each GPIO controller is packaged as a "struct gpio_chip" ++with information common to each controller of that type: ++ ++ - methods to establish GPIO direction ++ - methods used to access GPIO values ++ - flag saying whether calls to its methods may sleep ++ - optional debugfs dump method (showing extra state like pullup config) ++ - label for diagnostics ++ ++There is also per-instance data, which may come from device.platform_data: ++the number of its first GPIO, and how many GPIOs it exposes. ++ ++The code implementing a gpio_chip should support multiple instances of the ++controller, possibly using the driver model. That code will configure each ++gpio_chip and issue gpiochip_add(). Removing a GPIO controller should be ++rare; use gpiochip_remove() when it is unavoidable. ++ ++Most often a gpio_chip is part of an instance-specific structure with state ++not exposed by the GPIO interfaces, such as addressing, power management, ++and more. Chips such as codecs will have complex non-GPIO state, ++ ++Any debugfs dump method should normally ignore signals which haven't been ++requested as GPIOs. They can use gpiochip_is_requested(), which returns ++either NULL or the label associated with that GPIO when it was requested. ++ ++ ++Platform Support ++---------------- ++To support this framework, a platform's Kconfig will "select HAVE_GPIO_LIB" ++and arrange that its <asm/gpio.h> includes <asm-generic/gpio.h> and defines ++three functions: gpio_get_value(), gpio_set_value(), and gpio_cansleep(). ++They may also want to provide a custom value for ARCH_NR_GPIOS. ++ ++Trivial implementations of those functions can directly use framework ++code, which always dispatches through the gpio_chip: ++ ++ #define gpio_get_value __gpio_get_value ++ #define gpio_set_value __gpio_set_value ++ #define gpio_cansleep __gpio_cansleep ++ ++Fancier implementations could instead define those as inline functions with ++logic optimizing access to specific SOC-based GPIOs. For example, if the ++referenced GPIO is the constant "12", getting or setting its value could ++cost as little as two or three instructions, never sleeping. When such an ++optimization is not possible those calls must delegate to the framework ++code, costing at least a few dozen instructions. For bitbanged I/O, such ++instruction savings can be significant. ++ ++For SOCs, platform-specific code defines and registers gpio_chip instances ++for each bank of on-chip GPIOs. Those GPIOs should be numbered/labeled to ++match chip vendor documentation, and directly match board schematics. They ++may well start at zero and go up to a platform-specific limit. Such GPIOs ++are normally integrated into platform initialization to make them always be ++available, from arch_initcall() or earlier; they can often serve as IRQs. ++ ++ ++Board Support ++------------- ++For external GPIO controllers -- such as I2C or SPI expanders, ASICs, multi ++function devices, FPGAs or CPLDs -- most often board-specific code handles ++registering controller devices and ensures that their drivers know what GPIO ++numbers to use with gpiochip_add(). Their numbers often start right after ++platform-specific GPIOs. ++ ++For example, board setup code could create structures identifying the range ++of GPIOs that chip will expose, and passes them to each GPIO expander chip ++using platform_data. Then the chip driver's probe() routine could pass that ++data to gpiochip_add(). ++ ++Initialization order can be important. For example, when a device relies on ++an I2C-based GPIO, its probe() routine should only be called after that GPIO ++becomes available. That may mean the device should not be registered until ++calls for that GPIO can work. One way to address such dependencies is for ++such gpio_chip controllers to provide setup() and teardown() callbacks to ++board specific code; those board specific callbacks would register devices ++once all the necessary resources are available. +-- +1.5.3.8 + diff --git a/recipes/linux/linux-rp-2.6.24/tosa/0025-Signed-off-by-Dmitry-Baryshkov-dbaryshkov-gmail.co.patch b/recipes/linux/linux-rp-2.6.24/tosa/0025-Signed-off-by-Dmitry-Baryshkov-dbaryshkov-gmail.co.patch new file mode 100644 index 0000000000..84d0fd3e19 --- /dev/null +++ b/recipes/linux/linux-rp-2.6.24/tosa/0025-Signed-off-by-Dmitry-Baryshkov-dbaryshkov-gmail.co.patch @@ -0,0 +1,434 @@ +From 39717c1328f6aa13330eded0e0e268993cfd1eea Mon Sep 17 00:00:00 2001 +From: Dmitry Baryshkov <dbaryshkov@gmail.com> +Date: Tue, 12 Feb 2008 10:39:53 +0300 +Subject: [PATCH 25/64] Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> + +--- + arch/arm/mach-pxa/Makefile | 2 +- + arch/arm/mach-pxa/devices.c | 401 +++++++++++++++++++++++++++++++++++++++++++ + 2 files changed, 402 insertions(+), 1 deletions(-) + create mode 100644 arch/arm/mach-pxa/devices.c + +diff --git a/arch/arm/mach-pxa/Makefile b/arch/arm/mach-pxa/Makefile +index 5cb0216..f276d24 100644 +--- a/arch/arm/mach-pxa/Makefile ++++ b/arch/arm/mach-pxa/Makefile +@@ -4,7 +4,7 @@ + + # Common support (must be linked before board specific support) + obj-y += clock.o generic.o irq.o dma.o \ +- time.o gpio.o ++ time.o gpio.o devices.o + obj-$(CONFIG_PXA25x) += pxa25x.o + obj-$(CONFIG_PXA27x) += pxa27x.o + obj-$(CONFIG_PXA3xx) += pxa3xx.o mfp.o +diff --git a/arch/arm/mach-pxa/devices.c b/arch/arm/mach-pxa/devices.c +new file mode 100644 +index 0000000..928131a +--- /dev/null ++++ b/arch/arm/mach-pxa/devices.c +@@ -0,0 +1,401 @@ ++#include <linux/module.h> ++#include <linux/kernel.h> ++#include <linux/init.h> ++#include <linux/platform_device.h> ++#include <linux/dma-mapping.h> ++ ++#include <asm/arch/gpio.h> ++#include <asm/arch/udc.h> ++#include <asm/arch/pxafb.h> ++#include <asm/arch/mmc.h> ++#include <asm/arch/irda.h> ++#include <asm/arch/i2c.h> ++#include <asm/arch/ohci.h> ++ ++#include "devices.h" ++ ++#ifdef CONFIG_PXA25x ++ ++static u64 pxa25x_ssp_dma_mask = DMA_BIT_MASK(32);
