[PATCH 00/12] ARM: OMAP2+: powerdomain/PM: convert to functional power states

[Tero Kristo]

Hi Paul,

As mentioned with the previous set, I have tested this one also on
omap3beagle + omap4panda boards. omap4 has one regression caused by this
set, as commented on the patch itself. Also posted a couple of other
minor comments. Other than that, you can consider this set as acked by
me.
