Merge branch 'clps711x/soc' into next/soc
From Alexander Shiyan, this is a series of cleanups of clps711x, movig it
closer to multiplatform and cleans up a bunch of old code.
* clps711x/soc:
ARM: clps711x: Update defconfig
ARM: clps711x: Add support for SYSCON driver
ARM: clps711x: edb7211: Control LCD backlight via PWM
ARM: clps711x: edb7211: Add support for I2C
ARM: clps711x: Optimize interrupt handling
ARM: clps711x: Add clocksource framework
ARM: clps711x: Replace "arch_initcall" in common code with ".init_early"
ARM: clps711x: Move specific definitions from hardware.h to boards files
ARM: clps711x: p720t: Define PLD registers as GPIOs
ARM: clps711x: autcpu12: Move remaining specific definitions to board file
ARM: clps711x: autcpu12: Special driver for handling memory is removed
ARM: clps711x: autcpu12: Add support for NOR flash
ARM: clps711x: autcpu12: Move LCD DPOT definitions to board file
ARM: clps711x: Set PLL clock to zero if we work from 13 mHz source
ARM: clps711x: Remove NEED_MACH_MEMORY_H dependency
ARM: clps711x: Re-add GPIO support
GPIO: clps711x: Add DT support
GPIO: clps711x: Rewrite driver for using generic GPIO code
+ Linux 3.10-rc4
