Pull ARM SoC fixes from Olof Johansson:
 "A first set of batches of fixes for 3.13.  The diffstat is large
  mostly because we're adding a defconfig for a family that's been
  lacking it, and there's some missing clock information added for i.MX
  and OMAP.

  The at91 new code is around dealing with RTC/RTT reset at boot to fix
  possible hangs due to pending wakeup interrupts coming in during early
  boot"

OMAP SoC DES crypto Module

Required properties:

- compatible : Should contain "ti,omap4-des"
- ti,hwmods: Name of the hwmod associated with the DES module
- reg : Offset and length of the register set for the module
- interrupts : the interrupt-specifier for the DES module
- clocks : A phandle to the functional clock node of the DES module
corresponding to each entry in clock-names
- clock-names : Name of the functional clock, should be "fck"

Optional properties:
- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
Documentation/devicetree/bindings/dma/dma.txt
Each entry corresponds to an entry in dma-names
- dma-names: DMA request names should include "tx" and "rx" if present

Example:
/* DRA7xx SoC */
des: des@480a5000 {
compatible = "ti,omap4-des";
ti,hwmods = "des";
reg = <0x480a5000 0xa0>;
interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
dmas = <&sdma 117>, <&sdma 116>;
dma-names = "tx", "rx";
clocks = <&l3_iclk_div>;
clock-names = "fck";
};
