Cover letter [PATCH 00/10] ARM: OMAP2+: second set of PM fixes and cleanup for 3.9

Hi Paul,

I just tested this + next two powerdomain series from you on omap3beagle
+ omap4panda boards. This set seems fine, for the code I don't have any major complaints either, thus you can add my ack if you like. I'll send comments for the next two sets soon also.

Several more OMAP2+ power management fixes, optimizations, and cleanup, intended for 3.9. This series is also a prerequisite for the functional powerdomain conversion series.

I'll plan to bundle these patches together into a pull request with the first set of 3.9 PM patches, sent earlier.

- Paul
