[PATCH 1/8] ARM: OMAP2+: PM: introduce power domains functional states
Jean Pihet
jean.pihet at newoldbits.com
Wed Aug 15 06:02:41 EDT 2012
Introduce the functional states for power domains, which include
the power states and the logic states.
This patch provides the API functions to set and read the power
domains settings and to convert between the functional (i.e. logical)
and the internal (or registers) values.
OMAP2, OMAP3 and OMAP4 platforms are using common conversion routines.
In the new API only the function pwrdm_set_next_fpwrst shall be used
to change a power domain target state, along with the associated
PWRDM_FUNC_* and PWRDM_LOGIC_* macros as the state parameters.
