Hmm in patch 3/4 you add omap4_pwrdm_save_context(), I think
that we'd want to run with the notifier for cpuidle on omap4?
Okay i believe that is not needed for cpuidle on omap4. PRCM on wakeup
domain so save/restore not needed for powerdomain on omap4.
Tero can confirm the same.
Yea I don't believe this is needed. Only certain portions of the OMAP4
PRCM lose context during device off mode (which is currently not
supported by linux), and whatever portions do lose, they should use the
SAR_RAM approach for context save/restore, as that is supported by
HW/ROM code.
-Tero
Should i rename omap4_pwrdm_save_context to am43xx_pwrdm_save_context to
avoid confusion?
