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.
