OMAP2/3/4 clockdomains/powerdomains: split shared dependencies and clean up
Hi,
This series moves wakeup and sleep dependencies on the OMAP2/3 chips from
the powerdomain layer to the clockdomain layer, where they belong. It also
adds usecounting for clockdomain dependency usecounting, which fixes the
obvious problem that occurs when several different pieces of code need
to add clockdomain dependencies, and then one removes the dependency.
(To add usecounting, the dependencies that were shared between
clockdomains have been split into separate records.) These changes should
prepare the clockdomain code for OMAP4 clockdomain dependencies.
The series also does some cleanup. struct powerdomain is packed, the
dead function pwrdm_clk_state_switch() is removed, documentation is improved,
the nonexistent MDM clockdomain is removed from OMAP2420.
Boot-tested on N800, 2430SDP, and OMAP3 Beagle. Compile-tested with
omap_osk_5912_defconfig.
Applies on the 'for_2.6.34' branch of git://git.pwsan.com/linux-2.6
