Cover letter [PATCH 00/12] ARM: OMAP2+: powerdomain/PM: convert to functional power states
Hi
This series converts the OMAP2+ powerdomain and PM code to use "functional power states" - high-level power states such as "OSWR", which reflect changes in multiple underlying registers, rather than expecting high-level PM code to program the registers directly. This is intended to reduce the complexity of the high-level PM code and to make it easier to implement register caching of the various powerdomain registers, some of which are quite slow to access.
