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

+Cirrus Logic CLPS711X GPIO controller
+
+Required properties:
+- compatible: Should be "cirrus,clps711x-gpio"
+- reg: Physical base GPIO controller registers location and length.
+  There should be two registers, first is DATA register, the second
+  is DIRECTION.
+- gpio-controller: Marks the device node as a gpio controller.
+- #gpio-cells: Should be two. The first cell is the pin number and
+  the second cell is used to specify the gpio polarity:
+    0 = active high
+    1 = active low
+
+Note: Each GPIO port should have an alias correctly numbered in "aliases"
+node.
+
+Example:
+
+aliases {
+	gpio0 = &porta;
+};
+
+porta: gpio@80000000 {
+	compatible = "cirrus,clps711x-gpio";
+	reg = <0x80000000 0x1>, <0x80000040 0x1>;
+	gpio-controller;
+	#gpio-cells = <2>;

     }
 
+When in an active transaction that takes a signal, we need to be careful with
+the stack.  It's possible that the stack has moved back up after the tbegin.
+The obvious case here is when the tbegin is called inside a function that
+returns before a tend.  In this case, the stack is part of the checkpointed
+transactional memory state.  If we write over this non transactionally or in
+suspend, we are in trouble because if we get a tm abort, the program counter and
+stack pointer will be back at the tbegin but our in memory stack won't be valid
+anymore.
+
+To avoid this, when taking a signal in an active transaction, we need to use
+the stack pointer from the checkpointed state, rather than the speculated
+state.  This ensures that the signal context (written tm suspended) will be
+written below the stack required for the rollback.  The transaction is aborted
+becuase of the treclaim, so any memory written between the tbegin and the
+signal will be rolled back anyway.
+
+For signals taken in non-TM or suspended mode, we use the
+normal/non-checkpointed stack pointer.
