[PATCH V3 0/8] ARM: OMAP4: Add PMU Support

[Jon Hunter]

This series adds PMU support for OMAP4 devices. This is based upon Will Deacons
series [1] and re-based upon the latest arm-soc next/cleanup branch (3.6-rc3)
that includes Will's series. It has been re-based upon this series because
of the dependency on Sudeep KarkadaNagesha's change (ARM: pmu: remove
arm_pmu_type enumeration) [2] that modifies the OMAP PMU code.

This series is also dependent upon some clock fixes for OMAP3 [3] and OMAP4 [4]
for PMU to operate correctly on OMAP3 and OMAP4.

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.

Testing:
- Verified that PMU is working on OMAP2420 H4, OMAP3430 Beagle Board, OMAP4430
  Panda and OMAP4460 Panda.
- Tested on the above boards with CPU-idle enabled to ensure that PMU is working
  with power management. For OMAP3430 verified that CORE retention state is
  entered again after stopping PMU events.

V3 changes:
- Will Deacon has taken the PMU runtime PM adaption patch in his series and so
  not included here [1].
- Dropped my fix for managing the EMU power domain on OMAP4 in favour of Paul's
  implementation [4]. Paul is planning to submit for v3.7.
- Added HWMOD data for OMAP3 DEBUG sub-system. The DEBUG sub-system was always
  being enabled on OMAP3 devices when using PMU and hence, hinding the fact
  that PMU is dependent upon the DEBUG sub-system on OMAP3 for it to work.
