ARM: OMAP2+: PM: clean up omap_set_pwrdm_state()
Clean up a few different parts of omap_set_pwrdm_state():
- Remove a superfluous call to pwrdm_state_switch(). Not needed
unless LOWPOWERSTATECHANGE is used, because the state switch code is
called by either clkdm_sleep() or clkdm_allow_idle().
- Add code to wait for the power state transition in the OMAP4+ low
power state change. This is speculative, so I would particularly
appreciate feedback on this part.
- Remove a superfluous call to pwrdm_read_pwrst().
- Update variable names to be more meaningful (hopefully) and precise.
- Fix an error path bug that would not place the clockdomain back into
hardware-supervised idle or sleep mode if the power state could not
be programmed.
The documentation for this function still needs major improvements;
that's left for a later patch.
