| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arch_initcall() is too late for board initialisation to use gpiolib when doing their machine specific initilisation via the .init_machine callback.

| | * [ARM] S3C24XX: GPIO: Start removal of S3C24XX_GPIO_BASEBen Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The S3C24XX_GPIO_BASE makes it difficult to compress the GPIO number space, and is only used in a few places of which everything outside arch/arm/plat-s3c24xx/gpiolib.c will be removed as soon as possible. Change gpiolib.c to use the S3C2410_GPxCON register addresses as the base for each bank, thus eliminating S3C24XX_GPIO_BASE. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move all the gpio functions out of <mach/hardware.h> as this file is for defining the generic IO base addresses for the kernel IO calls. Make a new header <mach/gpio-fns.h> to take this and include it via the chain from <linux/gpio.h> which is what most of these files should be using (and will be changed as soon as possible). Note, this does make minor changes to some drivers but should not mess up any pending merges.

| | * [ARM] S3C24XX: GPIO: Remove pin specific input and output definesBen Dooks2009-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are very rare and are taking up large amounts of space in the regs-gpio.h header. The GPIO layer has had generic input and out defines called S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work for all S3C24XX GPIOs. Do the following replacements: S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT S3C2410_GP[A-Z][0-9]*_\INP => /S3C2410_GPIO_INPUT S3C2410_GPA[0-9]*_OUT => S3C2410_GPIO_OUTPUT to remove any usages of these and prepare the header for the removal of these. The following command was used to acheive this: find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g' Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the s3c2410_gpio_irq2pin() function as it is not being used in any in kernel driver and the function is probably not being used anywhere else. This is also part of the effort to remove any of the s3c24xx gpio specific code that cannot be recreated by using the gpiolib framework now in the kernel.

| * | [ARM] S3C: GPIO PM core GPIOlib integrationBen Dooks2009-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the GPIO suspend/resume support inline with the gpiolib support so that it will work with both the S3C24XX and S3C64XX series. The s3c_gpio_chip is extended to have a pm callback and a save block to keep the state of the GPIO over suspend, and the code from the s3c24xx implementation is added to a new common file. The suspend process now uses the list of registered chips to go through saving and restoring each one as appropriate, using the pm callback to select the appropriate routine depending on the type of control register present. This change also means that any additional GPIO added should not require changes to the PM. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted by Russell King, the sleep code path is not elegant and makes use of leaving items on the stack between calls. Change the code that does the following: if (s3c_cpu_save(regs_save) == 0) { flush_cache_all(); S3C_PMDBG("preparing to sleep\n"); pm_cpu_sleep(); } to simply call s3c_cpu_save, and let that do the necessary calls to quiesce and sleep the system.

This will also allow us to save the UDIVSLOT register on newer SoCs. Move to using a structure for the UART use the extant Kconfig configuration specifying the number of UARTs.

* / [ARM] pass reboot command line to arch_reset()Russell King2009-03-19
|/ | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.
