From: Jean Pihet <jean.pi...@newoldbits.com>
Use the functional power states as the API to control power domains:
- use the PWRDM_FUNC_PWRST_* macros for the power states and logic
settings,
- the function pwrdm_set_next_fpwrst(), which controls the power domains
next power and logic settings, shall be used instead of
pwrdm_set_next_pwrst() to program the power domains next states,
- the function pwrdm_set_fpwrst(), which programs the power domains
power and logic settings, shall be used instead of
omap_set_pwrdm_state().
Signed-off-by: Jean Pihet <j-pi...@ti.com>
[p...@pwsan.com: split the original patch into OMAP2/3/4 variants;
clean up omap3_save_secure_ram_context(); fix commit message;
warn if sets fail; various other changes]
