[PATCH 00/12] ARM: OMAP2+: powerdomain updates after the functional power state conversion

OMAP powerdomain code updates, implemented on top of the
functional power state conversion series.  This series fixes the powerdomain
handling for OMAP2xxx, adds caching for the powerdomain next-power-state
and previous-power-state register bitfields, and some cleanup that's
intended to make it easier to move the powerdomain code out to drivers/.

Paul Walmsley (12):
      ARM: OMAP2+: powerdomain: consolidate arch_pwrdm check code
      ARM: OMAP2+: PM/powerdomain: move the power state time tracking into the powerdomain code
      ARM: OMAP2+: powerdomain: split pwrdm_state_switch()
      ARM: OMAP2+: PM: clean up some debugfs functions
      ARM: OMAP2+: powerdomain: remove some redundant checks; add some notes
      ARM: OMAP2+: CM: use the cached copy of the clockdomain's hwsup state
      ARM: OMAP2+: powerdomain: cache the powerdomain next power state
      ARM: OMAP2+: powerdomain: cache the powerdomain's previous power state
      ARM: OMAP2+: powerdomain: skip register reads for powerdomains known to be on
      ARM: OMAP2+: powerdomain: skip previous-power-state read if next_pwrst is ON
      ARM: OMAP2xxx: powerdomain: add previous power state tracking
      ARM: OMAP2xxx: PM: add pwrdm_(pre|post)_transition() calls to the 2xxx PM code
