From: Jean Pihet <j-pihet@xxxxxx>
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

ARM: OMAP2+: PM: protect the power domain state change by a mutex
ARM: OMAP2+: PM: introduce power domains functional states
ARM: OMAP2+: PM: use the functional power states API
ARM: OMAP2+: PM: introduce power domains logic and memory functional
states
ARM: OMAP2+: PM: use the functional power states API for logic and
memory
ARM: OMAP2+: PM: use power domain functional state in stats counters
