* ARM: S3C24XX: Fix mess with gpio {set,get}_pull callbacksVasily Khoruzhick2010-12-081-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker error when only CONFIG_CPU_S3C2442 is selected: arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to `s3c_gpio_getpull_1up' arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to `s3c_gpio_setpull_1up' The s3c2442 has pulldowns instead of pullups compared to the s3c2440. The method of controlling them is the same though. So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions to take an additional parameter deciding whether the pin has a pullup or pulldown. The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN. Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields in the s3c244{0,2}_map_io function to the new pulldown helper functions.

* | ARM: S3C2440: fix boot failure introduced by recent changes in gpiolibAbdoulaye Walsimou Gaye2010-10-301-0/+2
|/ | | | | | | | | | | | | | Recent changes in s3c gpio break mini2440 board and may be others. The problem is that mach-mini2440.c: mini2440_init() (where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init() (where we initialize s3c24xx_gpiocfg_default.set_pull function pointer). This causes dereferencing of NULL pointer at boot time and a kernel panic.

* ARM: SAMSUNG: Add GPIO configuration read callsBen Dooks2010-05-061-0/+2
| | | | | | | Add the necessary 1,2 and 4 bit configuration read calls for the new gpio code to allow removal of the old s3c24xx gpio code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* ARM: S3C24XX: Add extended GPIO used on S3C2443 and beyondBen Dooks2010-05-061-1/+40
| | | | | | | | | | | Add the GPIO banks that are used on the S3C2443 and above to the list of available GPIOS. Currently we do not have any limit on the SoC GPIO, so these are being registered whether the SoC has them or not. It is currently up to the user not to try and use them.

* ARM: S3C24XX: Add initial s3c_gpio configuration codeBen Dooks2010-05-061-1/+16
| | | | | | | | | | Add support for s3c_gpio_setcfg() and s3c_gpio_setpull() implementations to get ready for removal of the specific code being used by s3c24xx. Also rename the s3c_gpio_setcfg_s3c24xx_banka to s3c_gpio_setcfg_s3c24xx_a as seen in the header file to correct a build warning. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* ARM: SAMSUNG: Remove empty gpio-core.h and use central plat/gpio-core.hBen Dooks2010-01-191-1/+1
| | | | | | | | | | Rename mach-s3c2410/include/mach/gpio-core.h to mach/gpio-track.h so that it can be included by <plat/gpio-core.h> when needed. Eliminate all other empty gpio-core.h files and just include the <plat/gpio-core.h> as necessary. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: GPIO: Fix missing GPIOs in gpiolibBen Dooks2009-05-181-1/+10

* [ARM] S3C24XX: GPIO: Move gpiolib initialisation earlierBen Dooks2009-05-181-1/+1
| | | | | | | | | | | 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>

| | | | | | | | | | | 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: Start removal of S3C24XX_GPIO_BASEBen Dooks2009-05-181-7/+7
| | | | | | | | | | | | 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: Fix missing <linux/sysdev.h>Ben Dooks2009-05-181-0/+1
| | | | | | | | | | | | | | In our recent changes, arch/arm/plat-s3c24xx/gpiolib.c needs to have <linux/sysdev.h> included for it to build.

* [ARM] S3C: GPIO PM core GPIOlib integrationBen Dooks2009-05-071-0/+8
| | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | All the s3c24xx gpiolib chips share the same get/set calls and all but one bank shares the same calls for .direction_input and .direction_output methods. Change the initialisation process to use an new call to register the chips that fills in any blank calls with the default values to avoid having to fill them in the structure initialisers.
