Rockchip processors include support for multiple power domains
|
||||
which can be powered up/down by software based on different
|
||||
application scenarios 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.

* 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,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>;
|
||||
/* ... */
|
||||
};
