This patch fixes the usecount tracking for omap3+, previously the
usecount numbers were rather bogus and were not really useful for
any purpose. Now usecount numbers track the number of really active
clients on each domain. This patch also adds support for usecount
tracking on powerdomain level and autoidle flag for clocks that
are hardware controlled and should be skipped in usecount
calculations.

kernel.  Proper error detection is preferred, but your usage, a
WARN_ON() should suffice.

Otherwise,
