1 * Rockchip Power Domains
3 Rockchip processors include support for multiple power domains which can be
4 powered up/down by software based on different application scenes to save power.
6 Required properties for power domain controller:
8 	"rockchip,px30-power-controller" - for PX30 SoCs.
9 	"rockchip,rk3036-power-controller" - for RK3036 SoCs.
10 	"rockchip,rk3066-power-controller" - for RK3066 SoCs.
11 	"rockchip,rk3128-power-controller" - for RK3128 SoCs.
12 	"rockchip,rk3188-power-controller" - for RK3188 SoCs.
13 	"rockchip,rk3228-power-controller" - for RK3228 SoCs.
14 	"rockchip,rk3288-power-controller" - for RK3288 SoCs.
15 	"rockchip,rk3328-power-controller" - for RK3328 SoCs.
16 	"rockchip,rk3366-power-controller" - for RK3366 SoCs.
17 	"rockchip,rk3368-power-controller" - for RK3368 SoCs.
18 	"rockchip,rk3399-power-controller" - for RK3399 SoCs.
19 - #power-domain-cells: Number of cells in a power-domain specifier.
24 Required properties for power domain sub nodes:
25 - reg: index of the power domain, should use macros in:
26 	"include/dt-bindings/power/px30-power.h" - for PX30 type power domain.

29 	"include/dt-bindings/power/rk3128-power.h" - for RK3128 type power domain.
30 	"include/dt-bindings/power/rk3188-power.h" - for RK3188 type power domain.
31 	"include/dt-bindings/power/rk3228-power.h" - for RK3228 type power domain.
32 	"include/dt-bindings/power/rk3288-power.h" - for RK3288 type power domain.
33 	"include/dt-bindings/power/rk3328-power.h" - for RK3328 type power domain.

36 	"include/dt-bindings/power/rk3399-power.h" - for RK3399 type power domain.
37 - clocks (optional): phandles to clocks which need to be enabled while power domain
40 	while power domain switches state.
51 	power: power-controller {
52 		compatible = "rockchip,rk3288-power-controller";
53 		#power-domain-cells = <1>;
64 	 power: power-controller {
65                 compatible = "rockchip,rk3368-power-controller";
66                 #power-domain-cells = <1>;
77 		power: power-controller {
78 			compatible = "rockchip,rk3399-power-controller";
79 			#power-domain-cells = <1>;
104 Node of a device using power domains must have a power-domains property,
105 containing a phandle to the power device node and an index specifying which
106 power domain to use.

118 Example of the node using power domain:
122 		power-domains = <&power RK3288_PD_GPU>;
128                 power-domains = <&power RK3368_PD_GPU_1>;
134 		power-domains = <&power RK3399_PD_VOPB>;
