Subject: ARM: OMAP4+: PM: Make logic state programmable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=46ba55265254e8f47f8c2af6408841f31bab4870;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ARM: OMAP4+: PM: Make logic state programmable

Move the logic state as different for each power domain. This allows us
to customize the deepest power state we should target over all for each
powerdomain in the follow on patches.
