Subject: arm64: dts: rockchip: Add power controller for RK3528
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=654df8e74dbc19ba0625051079e6889e6999d16e;p=thirdparty%2Flinux.git

arm64: dts: rockchip: Add power controller for RK3528

Add power-domain nodes for the power controller on RK3528.

Only PD_GPU can fully be powered down. PD_RKVDEC, PD_RKVENC, PD_VO and
PD_VPU are idle only power domains used by miscellaneous devices.

Because multiple of the miscellaneous device types currently complain
about the use of a power-domains prop, only PD_GPU is enabled.
