Signed-off-by: Oleksij Rempel <o.rempel@...gutronix.de> Reviewed-by: Andrew Lunn <andrew@...n.ch> --- changes v6: - add description of PSE controller - change "^ethernet-pse(@[a-f0-9]+)?$" to "^ethernet-pse(@.*)?$" changes v5: - rename to podl-pse-regulator.yaml - remove compatible description - remove "-1" on node name - add pse-controller.yaml for common properties changes v4: - rename to PSE regulator - drop currently unused properties - use own compatible for PoDL PSE changes v2: - rename compatible to more generic "ieee802.3-pse" - add class and type properties for PoDL and PoE variants - add pairs property --- .../net/pse-pd/podl-pse-regulator.yaml | 40 +++++++++++++++++++ .../bindings/net/pse-pd/pse-controller.yaml | 33 +++++++++++++++ 2 files changed, 73 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/pse-pd/podl-pse-regulator.yaml create mode 100644 Documentation/devicetree/bindings/net/pse-pd/pse-controller.yaml diff --git a/Documentation/devicetree/bindings/net/pse-pd/podl-pse-regulator.yaml b/Documentation/devicetree/bindings/net/pse-pd/podl-pse-regulator.yaml new file mode 100644 index 000000000000..c6b1c188abf7 --- /dev/null +++ b/Documentation/devicetree/bindings/net/pse-pd/podl-pse-regulator.yaml @@ -0,0 +1,40 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/pse-pd/podl-pse-regulator.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Regulator based Power Sourcing Equipment + +maintainers: + - Oleksij Rempel <o.rempel@...gutronix.de> + +description: Regulator based PoDL PSE controller.
