+description: |
+  Rockchip processors include support for multiple power domains which can be
+  powered up/down by software based on different application scenes to save power.
+
+  Power domains contained within power-controller node are generic power domain
+  providers documented in Documentation/devicetree/bindings/power/power-domain.yaml.
+
+  IP cores belonging to a power domain should contain a 'power-domains'
+  property that is a phandle for the power domain node representing the domain.

-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.

-
-	qos_gpu: qos_gpu@ffaf0000 {
-		compatible ="syscon";
-		reg = <0x0 0xffaf0000 0x0 0x20>;

-		#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";

-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>;
-                /* ... */

-		compatible ="syscon";
-		reg = <0x0 0xffaf0000 0x0 0x20>;
-	};

-		#size-cells = <0>;
-
-		pd_gpu {
-			reg = <RK3288_PD_GPU>;
-			clocks = <&cru ACLK_GPU>;

-
-	 power: power-controller {

-                };
-        };
-
-Example 2:

-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>;
-                /* ... */

-* 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/rk3228-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.
-- 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>;
-		/* ... */
-	};

This is not a theater.
=====
Scenes:
1. Something seen by a viewer; a view or prospect.
2. The place where an action or event occurs: the scene of the crime.

Scenarios:
1. An expected or supposed situation or sequence of events

This is not a theater.
=====
Scenes:
1. Something seen by a viewer; a view or prospect.
2. The place where an action or event occurs: the scene of the crime.

Scenarios:
1. An expected or supposed situation or sequence of events

scenes > scenarios ??

This is not a theater.
=====
Scenes:
1. Something seen by a viewer; a view or prospect.
2. The place where an action or event occurs: the scene of the crime.

Scenarios:
1. An expected or supposed situation or sequence of events
