Cc: Zoltan HERPAI Cc: Raylynn Knight Cc: devicetree@vger.kernel.org Signed-off-by: Linus Walleij --- ChangeLog v2->v3: - Designate phy nodes with ethernet-phy@ - Include phy-mode in the schema ChangeLog v1->v2: - Add schema for the (optional) embedded MDIO bus inside the ethernet controller in an "mdio" node instead of just letting the code randomly populate and present it to the operating system. - Reference the standard schemas for ethernet controller and MDIO buses. - Add intel,npe to indentify the NPE unit used with each ethernet adapter. --- .../bindings/net/intel,ixp4xx-ethernet.yaml | 82 +++++++++++++++++++ 1 file changed, 82 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/intel,ixp4xx-ethernet.yaml diff --git a/Documentation/devicetree/bindings/net/intel,ixp4xx-ethernet.yaml b/Documentation/devicetree/bindings/net/intel,ixp4xx-ethernet.yaml new file mode 100644 index 000000000000..978e7f236f3a --- /dev/null +++ b/Documentation/devicetree/bindings/net/intel,ixp4xx-ethernet.yaml @@ -0,0 +1,82 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +# Copyright 2018 Linaro Ltd. +%YAML 1.2 +--- +$id: "http://devicetree.org/schemas/net/intel,ixp4xx-ethernet.yaml#" +$schema: "http://devicetree.org/meta-schemas/core.yaml#" + +title: Intel IXP4xx ethernet + +allOf: + - $ref: "ethernet-controller.yaml#" + +maintainers: + - Linus Walleij + +description: | + The Intel IXP4xx ethernet makes use of the IXP4xx NPE (Network + Processing Engine) and the IXP4xx Queue Mangager to process + the ethernet frames.
