-Rockchip power-management-unit:
--------------------------------
-
-The pmu is used to turn off and on different power domains of the SoCs
-This includes the power to the CPU cores.
-
-Required node properties:
-- compatible value : = "rockchip,rk3066-pmu";
-- reg : physical base address and the size of the registers window
-
-Example:
-
-	pmu@20004000 {
-		compatible = "rockchip,rk3066-pmu";
-		reg = <0x20004000 0x100>;
-	};

-* Rockchip General Register Files (GRF)
-
-The general register file will be used to do static set by software, which
-is composed of many registers for system control.
-
-From RK3368 SoCs, the GRF is divided into two sections,
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- PMUGRF, used for always on system
-
-On RK3328 SoCs, the GRF adds a section for USB2PHYGRF,
-
-ON RK3308 SoC, the GRF is divided into four sections:
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- DETECTGRF, used for audio codec system,
-- COREGRF, used for pvtm,
-
-Required Properties:
-
-- compatible: GRF should be one of the following:
-   - "rockchip,px30-grf", "syscon": for px30

-- #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.

-- 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.

-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>;
-		/* ... */
