2012-07-13ARM: vexpress: Initial common clock supportPawel Moll
This patch makes Versatile Express use the common clock framework instead of the plat-versatile implementation. It defines clock provider for VE's OSCs (clock generators) and registers all required fixed and variable clock sources (for both motherboard and core tile). This is a simple conversion of the existing state and will be extended (and migrated to drivers/clk) in the near future. Signed-off-by: Pawel Moll <pawel.moll@arm.com>

2012-07-13ARM: S3C24XX: Remove unused GPIO definitions for port JSylwester Nawrocki
There is no need now for individual GPIO port J pin control bit definitions, the GPIO0..12 pins can be configured using the gpiolib API. The GPJ* register address offset definitions for S3C2413 are moved to the common mach-s3c24xx/include/mach/regs-gpio.h header. These are still used outside of the gpio-samsung driver by PM code. Switching GPJ port to camera function can be done for example with: s3c_gpio_cfgall_range(S3C2410_GPJ(0), 13, S3C_GPIO_SFN(2), S3C_GPIO_PULL_NONE); Signed-off-by: Sylwester Nawrocki <sylvester.nawrocki@gmail.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2012-07-13Input: spear_keyboard - reconfigure operating frequency on suspendShiraz Hashim
On some platform it may happen that the input clock to keyboard may change during suspend, thus impacting its wakeup capability. There is no means for keyboard driver to know this frequency before hand. Hence introduce a platform data 'suspended_rate' which indicates the frequency during suspend at which keyboard operates. Accordingly reprogram keyboard while going into suspend and restore original configuration at the time of resume.
