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.
