[PATCH V2 00/10] ARM: OMAP4: Add PMU Support

[Jon Hunter]

This series adds PMU support for OMAP4 devices. This is based upon Will Deacons
series [1]. This series fixes the management of the EMU power domain so that
PMU can be enabled at runtime and low-power states are not prevented when PMU
is not in-use. The fix is based upon inputs from Benoit, Paul and Kevin [2].

This series also converts OMAP2/3 devices to use HWMOD to create the PMU device
and add a new file to mach-omap2 directory called pmu.c where the PMU devices
are created.

This series is based upon the latest linux-omap master branch from Tony
(3.5-rc1).

Testing:
- Verified that PMU is working on OMAP3430 Beagle Board, OMAP4430 Blaze and
  4460 Panda.
- Tested on the above boards with CPU-idle enabled to ensure that PMU is working
  with power management. For OMAP4 boards I have disabled CPU1 so that CPU0 and
  hence the MPU power domain is reaching the low-power retention state.
- I have booted the kernel on an OMAP2430 SDP but not verified PMU is working.
- Unable to verify 4470 Blaze because kernel is not currently booting.
