[PATCH v3 0/6] ARM: OMAP2+: PM: introduce the power domains functional states

[jean.pihet at newoldbits.com]

From: Jean Pihet <j-pihet at ti.com>

Implement the functional states for the power domains:
- protect the power domain state change by a mutex in
  omap_set_pwrdm_state,
- introduce the functional states for power domains power states and
  logic power states, and the conversion functions between the
  functional and internal states,
- unify the API to use the functional states,
- program the logic power state of power domains from the functional
  states, in omap_set_pwrdm_state
- convert the OMAP2/3/4 PM code to use the updated API,
- provide the power domains statistics by functional states.

Tested on OMAP3 Beagleboard, with suspend and cpuidle in RET and
OFF modes.


History:
 v3:
 - fix a bug in OMAP3 cpuidle which prevented the IO wake-ups in PER

 v2:
 - add the logic power states,
 - provide the power domains statistics by functional states

 v1:
 - initial implementation, in RFC state
