| | * [ARM] S3C24XX: GPIO: Move gpiolib initialisation earlierBen Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arch_initcall() is too late for board initialisation to use gpiolib when doing their machine specific initilisation via the .init_machine callback. Bring the file into line with the s3c64xx implementation and use the core_initcall() to register the GPIO chips. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| | * [ARM] S3C24XX: GPIO: Fix error returns from gpio functionsBen Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | Several GPIO functions have been returning -1 to indicate an error instead of returning a proper error code. Change to return -EINVAL for invalid argument(s). Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| | * [ARM] S3C24XX: GPIO: Change to macros for GPIO numberingBen Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare to remove the large number of S3C2410_GPxn defines by moving to S3C2410_GPx(n) in arch/arm. The following perl was used to change the files: perl -pi~ -e 's/S3C2410_GP([A-Z])([0-9]+)([^_^0-9])/S3C2410_GP\1\(\2\)\3/g' Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| | * [ARM] S3C24XX: GPIO: Add S3C64XX style GPIO numberingBen Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | Move the new style of GPIO numbering by using a single macro for each GPIO bank. This means S3C2410_GPA0 becomes S3C2410_GPA(0), and so on. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| | * [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>
| | * [ARM] S3C24XX: GPIO: Clean out unused definitions in <mach/regs-gpio.h>Ben Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The <mach/regs-gpio.h> really does not need the input and output pin configurations as these are standard and have a generic representation (plus the s3c24xx gpio specific code is going to be phased out soon). The following sed was applied to remove the lines: sed -i~ -e '/S3C2410_GP[A-Z][0-9]*_\INP/d' \ -e '/S3C2410_GP[A-Z][0-9]*_\OUTP/d' \ -e '/S3C2410_GPA[0-9]*_OUT/d' to remove these.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In our recent changes, arch/arm/plat-s3c24xx/gpiolib.c needs to have <linux/sysdev.h> included for it to build.

| | * [ARM] S3C24XX: GPIO: Move gpio functions out of <mach/hardware.h>Ben Dooks2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 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.

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>
