[PATCHv2 0/8] arm: omap: clk/clkdm/pwrdm/voltdm usecounting changes

[Tero Kristo]

Changes compared to previous version:

- moved voltdm_pwrdm_enable / disable hooks from idle code to
  pwrdm_pre_transition / pwrdm_post_transition functions (patch 4)
- added patches 7 and 8 to fix one issue that was visible with off-mode
  on omap3: attempting to disable wkdeps for per_clkdm causes crash
  dumps to be generated by omap_l3_smx (this was actually part of the
  original larger set but I dropped it accidentally from v1), this issue
  surfaces with this patch set as the kernel actually tries to manually
  idle per_clkdm (probably first time in history)
- added some parameter sanity checks (pwrdm/voltdm = null checks)

Similar tests done as with previous version, additionally off-mode tests
with omap3.
