* ARM: s3c64xx: Leave disabling of unused PM domains to genpdUlf Hansson2014-09-08
| | | | | | | | | Since genpd at late init, will try to disable unused PM domains we don't need to do it from the machine specific code as well.

* ARM: S3C[24|64]xx: move includes back under <mach/> scopeLinus Walleij2014-01-14
| | | | | | | | | | | | | | | | | | | | | | | When refactoring and breaking out the includes for the machine-specific GPIO configuration, two files were created in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as that namespace shall be used for defining data exchanged between machines and drivers, using it for these broad macros and config settings is wrong. Move the headers back into the machine-local <mach/gpio-samsung.h> file and think about the next step.

* ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij2013-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.
