Merge tag 'msm-dt-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/dt

From David Brown:

These patches migrate both the 8660 and 8960 targets on msm to be
devicetree only.  This also sets most of the frame in place necessary
to build both targets into the same image.

There's a couple of cleanups in here that are kept in this series
because they are intimately tied to the changes necessary to support
the devicetree conversions.

By Stephen Boyd
via David Brown
* tag 'msm-dt-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
  ARM: msm: Remove non-DT targets from 8960
  ARM: msm: Add DT support for 8960
  ARM: msm: Move io mapping prototypes to common.h
  ARM: msm: Rename board-msm8x60 to signify its DT only status
  ARM: msm: Make 8660 a DT only target
  ARM: msm: Move 8660 to DT timer
  ARM: msm: Add DT support to msm_timer
  ARM: msm: Allow timer.c to compile on multiple targets
  ARM: msm: Don't touch GIC registers outside of GIC code
  ARM: msm: Add msm8660-surf.dts to Makefile.boot
  ARM: msm: Add handle_irq handler for 8660 DT machine

Resolved trivial context conflict in arch/arm/mach-msm/io.c and a
remove/change conflict in arch/arm/mach-msm/board-msm8x60.c.
