Device tree conversions for samsung and tegra Both platforms had some initial device tree support, but this adds much more to actually make it usable. * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (45 commits) ARM: dts: Add intial dts file for EXYNOS4210 SoC, SMDKV310 and ORIGEN ARM: EXYNOS: Add Exynos4 device tree enabled board file rtc: rtc-s3c: Add device tree support input: samsung-keypad: Add device tree support ARM: S5PV210: Modify platform data for pl330 driver ARM: S5PC100: Modify platform data for pl330 driver ARM: S5P64x0: Modify platform data for pl330 driver ARM: EXYNOS: Add a alias for pdma clocks ARM: EXYNOS: Limit usage of pl330 device instance to non-dt build ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappers DMA: PL330: Add device tree support ARM: EXYNOS: Modify platform data for pl330 driver DMA: PL330: Infer transfer direction from transfer request instead of platform data DMA: PL330: move filter function into driver serial: samsung: Fix build for non-Exynos4210 devices serial: samsung: add device tree support serial: samsung: merge probe() function from all SoC specific extensions serial: samsung: merge all SoC specific port reset functions ARM: SAMSUNG: register uart clocks to clock lookup list serial: samsung: remove all uses of get_clksrc and set_clksrc ... Fix up fairly trivial conflicts in arch/arm/mach-s3c2440/clock.c and drivers/tty/serial/Kconfig both due to just adding code close to changes.

2012-01-02gpio: Explicitly index samsung_gpio_cfgsMark Brown1-10/+19
Make it easier to follow the by number references into samsung_gpio_cfgs by putting the indexes into the code initialising the array, improving readability a bit. Ideally we wouldn't be using magic array indexes at all but this is easier than coming up with a better way.

2011-12-23gpio/samsung: Add device tree support for EXYNOS4Thomas Abraham1-0/+72
As gpio chips get registered, a device tree node which represents the gpio chip is searched and attached to it. A translate function is also provided to convert the gpio specifier into actual platform settings for pin function selection, pull up/down and driver strength settings.

2011-12-22driver-core: remove sysdev.h usage.Kay Sievers1-1/+1
The sysdev.h file should not be needed by any in-kernel code, so remove the .h file from these random files that seem to still want to include it. The sysdev code will be going away soon, so this include needs to be removed no matter what.

2011-10-18gpio/samsung: Complain loudly if we don't know the SoCMark Brown1-0/+3
If we don't know the SoC type then we won't add any chips which is rather unfortunate as neither GPIO nor pinmux APIs will work, breaking lots of different subsystems. Logging at least provides a hint to the user as to what's gone wrong. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-10-12gpio/samsung: Move SoC specific codes within macroTushar Behera1-0/+10
In drivers/gpio/gpio-samsung.c, there are certain structures and functions which are not getting used if the particular CPU is not selected. These code segments are moved under CPU specific macros to remove compilation warnings.

2011-10-12gpio/samsung: Fix incorrect gpio pull up/down callback for EXYNOS4Thomas Abraham1-12/+19
Some of the gpio chips of exynos4 are assigned a default gpio config without the exynos4 specific pull up/down callbacks which resulted in incorrect setting of pull up/down configuration. Fix this by adding two new exynos4 specific entries in the array of default configs with set_pull and get_pull callbacks set to exynos4 specific callbacks The new default gpio configs can then be used for exynos4 gpio chips.

2011-10-12gpio/samsung: only register available gpio banksPeter Korsgaard1-0/+4
Only register gpio banks provided by SoC instead of the maximum possible to lessen confusion, get rid of a warning from gpiolib and stop it from eating into the extra gpios for configs with S3C24XX_GPIO_EXTRA != 0.

2011-10-04gpio/samsung: correct pin configuration for S5PC100/S5PC110/EXYNOS4Marek Szyprowski1-15/+15
Commit 1b39d5f2cc introduced new common gpio driver for all Samsung GPIO SoCs. The new driver use wrong configuration setup for all gpio pins on S5PC100 and S5PV210 SoCs and external interrupt lines on Exynos4 SoCs. This patch fixes this issue.

Commit 1b39d5f2cc introduced new common gpio driver for all Samsung GPIO SoCs. The new driver doesn't correctly register GPIO interrupts on Samsung Exynos4 SoCs.

2011-09-21gpio/samsung: gpio-samsung.c to support Samsung GPIOsKukjin Kim1-0/+2686
This patch adds support for Samsung GPIOs with one gpio driver and removes old GPIO drivers which are drivers/gpio-s3c24xx.c, gpio-s3c64xx.c, gpio-s5p64x0.c, gpio-s5pc100.c, gpio-s5pv210.c, gpio-exynos4.c, gpio-plat-samsung.c, plat-samsung/gpio-config.c and gpio.c to support each Samsung SoCs before. Because the gpio-samsung.c can replace old Samsung GPIO drivers. Basically, the gpio-samsung.c has been made by their merging and removing duplicated definitions. Note: gpio-samsung.c includes some SoC dependent codes and it will be replaced next time.
