Merge branch 'spear-for-3.8' of git://git.linaro.org/people/vireshk/linux into next/dt2

From Viresh Kumar <viresh.kumar@linaro.org>:

These are DT updates for SPEAr SoCs. There aren't any fixes that we want
to get into 3.7-rc* and we are happy with 3.8.

Some of the dtbs which use gpiopinctrl have dependency on Linus's
pinctrl tree, where an earlier update for adding gpiopinctrl node is present.

* 'spear-for-3.8' of git://git.linaro.org/people/vireshk/linux:
  ARM: SPEAr3xx: Shirq: Move shirq controller out of plat/
  ARM: SPEAr320: DT: Add SPEAr 320 HMI board support
  ARM: SPEAr3xx: DT: add shirq node for interrupt multiplexor
  ARM: SPEAr3xx: shirq: simplify and move the shared irq multiplexor to DT
  ARM: SPEAr1310: Fix AUXDATA for compact flash controller
  ARM: SPEAr13xx: Remove fields not required for ssp controller
  ARM: SPEAr1310: Move 1310 specific misc register into machine specific files
  ARM: SPEAr: DT: Update device nodes
  ARM: SPEAr: DT: add uart state to fix warning
  ARM: SPEAr: DT: Modify DT bindings for STMMAC
  ARM: SPEAr: DT: Fix existing DT support
  ARM: SPEAr: DT: Update partition info for MTD devices
  ARM: SPEAr: DT: Update pinctrl list
  ARM: SPEAr13xx: DT: Add spics gpio controller nodes
