Signed-off-by: Lukasz Majewski --- Changes for v2: - Rename the file to match exactly the compatible (nxp,imx287-mtip-switch) Changes for v3: - Remove '-' from const:'nxp,imx287-mtip-switch' - Use '^port@[12]+$' for port patternProperties - Drop status = "okay"; - Provide proper indentation for 'example' binding (replace 8 spaces with 4 spaces) - Remove smsc,disable-energy-detect; property - Remove interrupt-parent and interrupts properties as not required - Remove #address-cells and #size-cells from required properties check - remove description from reg: - Add $ref: ethernet-switch.yaml# Changes for v4: - Use $ref: ethernet-switch.yaml#/$defs/ethernet-ports and remove already referenced properties - Rename file to nxp,imx28-mtip-switch.yaml --- .../bindings/net/nxp,imx28-mtip-switch.yaml | 126 ++++++++++++++++++ 1 file changed, 126 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/nxp,imx28-mtip-switch.yaml diff --git a/Documentation/devicetree/bindings/net/nxp,imx28-mtip-switch.yaml b/Documentation/devicetree/bindings/net/nxp,imx28-mtip-switch.yaml new file mode 100644 index 000000000000..1afaf8029725 --- /dev/null +++ b/Documentation/devicetree/bindings/net/nxp,imx28-mtip-switch.yaml @@ -0,0 +1,126 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/nxp,imx28-mtip-switch.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: NXP SoC Ethernet Switch Controller (L2 MoreThanIP switch) + +maintainers: + - Lukasz Majewski + +description: + The 2-port switch ethernet subsystem provides ethernet packet (L2) + communication and can be configured as an ethernet switch.
