Changes in v5:
- Fix space warnings reported by bot.
- Add the Rob's Reviewed-by tag.
- Fix license.
Changes in v4:
- Use hex for unit-addresses.
- Use space between compatibles in the example.
- Define child nodes for nested power domains even are duplicated but
more clear that adding a regex scaped to be a valid URI.
Changes in v3:
- Fixed tab errors found by bot
Changes in v2:
- Fixed a warning that says that 'syscon' should not be used alone.
- Use patternProperties to define a new level for power-domains.
- Add const values for power-domain-cells, address-cells, etc.

-* Rockchip Power Domains
-
-Rockchip processors include support for multiple power domains which can be
-powered up/down by software based on different application scenes to save power.
-
-Required properties for power domain controller:
-- compatible: Should be one of the following.
- "rockchip,px30-power-controller" - for PX30 SoCs.
- "rockchip,rk3036-power-controller" - for RK3036 SoCs.
- "rockchip,rk3066-power-controller" - for RK3066 SoCs.
- "rockchip,rk3128-power-controller" - for RK3128 SoCs.
- "rockchip,rk3188-power-controller" - for RK3188 SoCs.
- "rockchip,rk3228-power-controller" - for RK3228 SoCs.
- "rockchip,rk3288-power-controller" - for RK3288 SoCs.
- "rockchip,rk3328-power-controller" - for RK3328 SoCs.
- "rockchip,rk3366-power-controller" - for RK3366 SoCs.
- "rockchip,rk3368-power-controller" - for RK3368 SoCs.
- "rockchip,rk3399-power-controller" - for RK3399 SoCs.
-- #power-domain-cells: Number of cells in a power-domain specifier.
- Should be 1 for multiple PM domains.
-- #address-cells: Should be 1.
-- #size-cells: Should be 0.
-
-Required properties for power domain sub nodes:
-- reg: index of the power domain, should use macros in:
- "include/dt-bindings/power/px30-power.h" - for PX30 type power domain.
- "include/dt-bindings/power/rk3036-power.h" - for RK3036 type power domain.
- "include/dt-bindings/power/rk3066-power.h" - for RK3066 type power domain.
- "include/dt-bindings/power/rk3128-power.h" - for RK3128 type power domain.
- "include/dt-bindings/power/rk3188-power.h" - for RK3188 type power domain.

- "include/dt-bindings/power/rk3399-power.h" - for RK3399 type power domain.
-- clocks (optional): phandles to clocks which need to be enabled while power domain
- switches state.
-- pm_qos (optional): phandles to qos blocks which need to be saved and restored
- while power domain switches state.

-Qos Example:
-
- qos_gpu: qos_gpu@ffaf0000 {
- compatible ="syscon";
- reg = <0x0 0xffaf0000 0x0 0x20>;
- };
-
-Example:
-
- power: power-controller {
- compatible = "rockchip,rk3288-power-controller";
- #power-domain-cells = <1>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- pd_gpu {
- reg = <RK3288_PD_GPU>;
- clocks = <&cru ACLK_GPU>;
- pm_qos = <&qos_gpu>;
- };
- };
-
- power: power-controller {
- compatible = "rockchip,rk3368-power-controller";
- #power-domain-cells = <1>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- pd_gpu_1 {
- reg = <RK3368_PD_GPU_1>;
- clocks = <&cru ACLK_GPU_CFG>;
- };
- };
-
-Example 2:
- power: power-controller {
- compatible = "rockchip,rk3399-power-controller";
- #power-domain-cells = <1>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- pd_vio {
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <RK3399_PD_VIO>;
-
- pd_vo {
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <RK3399_PD_VO>;
-
- pd_vopb {
- reg = <RK3399_PD_VOPB>;
- };
-
- pd_vopl {
- reg = <RK3399_PD_VOPL>;
- };
- };
- };
- };
-
-Node of a device using power domains must have a power-domains property,
-containing a phandle to the power device node and an index specifying which
-power domain to use.
-The index should use macros in:
- "include/dt-bindings/power/px30-power.h" - for px30 type power domain.
- "include/dt-bindings/power/rk3036-power.h" - for rk3036 type power domain.
- "include/dt-bindings/power/rk3128-power.h" - for rk3128 type power domain.
- "include/dt-bindings/power/rk3128-power.h" - for rk3228 type power domain.
- "include/dt-bindings/power/rk3288-power.h" - for rk3288 type power domain.
- "include/dt-bindings/power/rk3328-power.h" - for rk3328 type power domain.
- "include/dt-bindings/power/rk3366-power.h" - for rk3366 type power domain.
- "include/dt-bindings/power/rk3368-power.h" - for rk3368 type power domain.
- "include/dt-bindings/power/rk3399-power.h" - for rk3399 type power domain.
-
-Example of the node using power domain:
-
- node {
- /* ... */
- power-domains = <&power RK3288_PD_GPU>;
- /* ... */
- };
-
- node {
- /* ... */
- power-domains = <&power RK3368_PD_GPU_1>;
- /* ... */
- };
-
- node {
- /* ... */
- power-domains = <&power RK3399_PD_VOPB>;
