Signed-off-by: Kory Maincent Reviewed-by: Andrew Lunn --- Changes in v2: - Enhance ports-matrix description. - Replace additionalProperties by unevaluatedProperties. - Drop i2c suffix. Changes in v3: - Remove ports-matrix parameter. - Add description of all physical ports and managers. - Add pse_pis subnode moving to the API of pse-controller binding. - Remove the MAINTAINERS section for this driver as I will be maintaining all pse-pd subsystem. Changes in v5: - Remove defs used only once. - Replace underscore by dash. - Add description. Changes in v7: - Fix nit. - Add vpwr-supply property in the example. - Remove ports references for the manager node. --- .../bindings/net/pse-pd/microchip,pd692x0.yaml | 169 +++++++++++++++++++++ 1 file changed, 169 insertions(+) diff --git a/Documentation/devicetree/bindings/net/pse-pd/microchip,pd692x0.yaml b/Documentation/devicetree/bindings/net/pse-pd/microchip,pd692x0.yaml new file mode 100644 index 000000000000..828439398fdf --- /dev/null +++ b/Documentation/devicetree/bindings/net/pse-pd/microchip,pd692x0.yaml @@ -0,0 +1,169 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/pse-pd/microchip,pd692x0.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Microchip PD692x0 Power Sourcing Equipment controller + +maintainers: + - Kory Maincent + +allOf: + - $ref: pse-controller.yaml# + +properties: + compatible: + enum: + - microchip,pd69200 + - microchip,pd69210 + - microchip,pd69220 + + reg: + maxItems: 1 + + managers: + type: object + description: + List of the PD69208T4/PD69204T4/PD69208M PSE managers.
