Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

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>;
