From: Jean Pihet <j-pihet@xxxxxx>
Use the functional power states as the API to control power domains.
The omap_set_pwrdm_state function shall be used instead of
pwrdm_set_next_pwrst to control the power domains next states.
Note: the internal code for power domains state management still
uses the internal power states.
