The RK3399 PMU is dedicated for managing the power of the whole chip. 1. add pd node for RK3399 Soc 2. create power domain tree 3. add qos node for domain From the DT/binds and driver can get more detail information: The driver: drivers/soc/rockchip/pm_domains.c The document: Documentation/devicetree/bindings/soc/rockchip/power_domain.txt --- Tested on vop and gpu devices added for next kernel.
