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

1 | Cirrus Logic CLPS711X GPIO controller | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: Should be "cirrus,clps711x-gpio" | ||
5 | - reg: Physical base GPIO controller registers location and length. | ||
6 | There should be two registers, first is DATA register, the second | ||
7 | is DIRECTION. | ||
8 | - gpio-controller: Marks the device node as a gpio controller. | ||
9 | - #gpio-cells: Should be two. The first cell is the pin number and | ||
10 | the second cell is used to specify the gpio polarity: | ||
11 | 0 = active high | ||
12 | 1 = active low | ||
13 | |||
14 | Note: Each GPIO port should have an alias correctly numbered in "aliases" | ||
15 | node. | ||

19 | aliases { | ||
20 | gpio0 = &porta; | ||
21 | }; | ||
22 | |||
