Signed-off-by: Biju Das Reviewed-by: Rob Herring --- v4->v5: * Added Rb tag from Rob. v3->v4: * Replaced companion->renesas,gpt for the phandle to gpt instance * Replaced renesas,id->renesas,poeg-id * Removed default from renesas,poeg-id as default for a required property doesn't make much sense. * Updated the example and required properties with above changes v2->v3: * Removed Rb tag from Rob as there are some changes introduced. * Added companion property, so that poeg can link with gpt device * Documented renesas,id, as identifier for POEGG{A,B,C,D}. * Updated the example. v1->v2: * Updated the description. REF->v1: * Modelled as pincontrol as most of its configuration is intended to be static. * Updated reg size in example. --- .../bindings/pinctrl/renesas,rzg2l-poeg.yaml | 86 +++++++++++++++++++ 1 file changed, 86 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-poeg.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-poeg.yaml b/Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-poeg.yaml new file mode 100644 index 000000000000..ab2d456c93e4 --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-poeg.yaml @@ -0,0 +1,86 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/renesas,rzg2l-poeg.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Renesas RZ/G2L Port Output Enable for GPT (POEG) + +maintainers: + - Biju Das + +description: | + The output pins(GTIOCxA and GTIOCxB) of the general PWM timer (GPT) can be + disabled by using the port output enabling function for the GPT (POEG). + Specifically, either of the following ways can be used. + * Input level detection of the GTETRGA to GTETRGD pins. + * Output-disable request from the GPT. + * SSF bit setting(ie, by setting POEGGn.SSF to 1) + + The state of the GTIOCxA and the GTIOCxB pins when the output is disabled, + are controlled by the GPT module. + +properties: + compatible: + items: + - enum: + - renesas,r9a07g044-poeg # RZ/G2{L,LC} + - renesas,r9a07g054-poeg # RZ/V2L + - const: renesas,rzg2l-poeg + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + maxItems: 1 + + power-domains: + maxItems: 1 + + resets: + maxItems: 1 + + renesas,gpt: + $ref: /schemas/types.yaml#/definitions/phandle + description: phandle to gpt instance that serves the pwm operation. + + renesas,poeg-id: + $ref: /schemas/types.yaml#/definitions/uint32 + enum: [ 0, 1, 2, 3 ] + description: | + POEG group index.
