Signed-off-by: Enric Balletbo i Serra Reviewed-by: Rob Herring --- Changes in v6: - Add "rockchip," prefix to the qos compatible name. (Johan Jonker) 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. .../power/rockchip,power-controller.yaml | 283 ++++++++++++++++++ .../bindings/soc/rockchip/power_domain.txt | 136 --------- 2 files changed, 283 insertions(+), 136 deletions(-) create mode 100644 Documentation/devicetree/bindings/power/rockchip,power-controller.yaml delete mode 100644 Documentation/devicetree/bindings/soc/rockchip/power_domain.txt diff --git a/Documentation/devicetree/bindings/power/rockchip,power-controller.yaml b/Documentation/devicetree/bindings/power/rockchip,power-controller.yaml new file mode 100644 index 000000000000..3f4005be200b --- /dev/null +++ b/Documentation/devicetree/bindings/power/rockchip,power-controller.yaml @@ -0,0 +1,283 @@ +# SPDX-License-Identifier: GPL-2.0-only +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/power/rockchip,power-controller.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Rockchip Power Domains + +maintainers: + - Caesar Wang + - Heiko Stuebner + +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. + +properties: + $nodename: + const: power-controller + + compatible: + enum: + - rockchip,px30-power-controller + - rockchip,rk3036-power-controller + - rockchip,rk3066-power-controller + - rockchip,rk3128-power-controller + - rockchip,rk3188-power-controller + - rockchip,rk3228-power-controller + - rockchip,rk3288-power-controller + - rockchip,rk3328-power-controller + - rockchip,rk3366-power-controller + - rockchip,rk3368-power-controller + - rockchip,rk3399-power-controller + + '#power-domain-cells': + const: 1 + + '#address-cells': + const: 1 + + '#size-cells': + const: 0 + +patternProperties: + "^power-domain@[0-9a-f]+$": + type: object + description: | + Represents the power domains within the power controller node as documented + in Documentation/devicetree/bindings/power/power-domain.yaml. + + properties: + + '#power-domain-cells': + description: + Must be 0 for nodes representing a single PM domain and 1 for nodes + providing multiple PM domains. + + '#address-cells': + const: 1 + + '#size-cells': + const: 0 + + reg: + description: | + Power domain index.
