Convert enetc device binding file to yaml. Split to 3 yaml files, 'fsl,enetc.yaml', 'fsl,enetc-mdio.yaml', 'fsl,enetc-ierb.yaml'. Additional Changes: - Add pci<vendor id>,<production id> in compatible string. - Ref to common ethernet-controller.yaml and mdio.yaml. - Add Wei fang, Vladimir and Claudiu as maintainer. - Update ENETC description. - Remove fixed-link part. Signed-off-by: Frank Li <Frank.Li@xxxxxxx> --- Change from v2 to v3 - use endpoint-config as node name for fsl,enetc-ierb.yaml, - wrap to 80 in fsl,enetc-ierb.yaml. - fix unit address don't match - Remove reg/compatible string for pci - Add pci-device.yaml, which need absolute path. - Use example which have mdio sub node. Change from v1 to v2 - renamee file as fsl,enetc-mdio.yaml, fsl,enetc-ierb.yaml, fsl,enetc.yaml - example include pcie node --- .../bindings/net/fsl,enetc-ierb.yaml | 38 ++++++ .../bindings/net/fsl,enetc-mdio.yaml | 57 +++++++++ .../devicetree/bindings/net/fsl,enetc.yaml | 66 ++++++++++ .../devicetree/bindings/net/fsl-enetc.txt | 119 ------------------ 4 files changed, 161 insertions(+), 119 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/fsl,enetc-ierb.yaml create mode 100644 Documentation/devicetree/bindings/net/fsl,enetc-mdio.yaml create mode 100644 Documentation/devicetree/bindings/net/fsl,enetc.yaml delete mode 100644 Documentation/devicetree/bindings/net/fsl-enetc.txt diff --git a/Documentation/devicetree/bindings/net/fsl,enetc-ierb.yaml b/Documentation/devicetree/bindings/net/fsl,enetc-ierb.yaml new file mode 100644 index 0000000000000..c8a654310b905 --- /dev/null +++ b/Documentation/devicetree/bindings/net/fsl,enetc-ierb.yaml @@ -0,0 +1,38 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/fsl,enetc-ierb.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Integrated Endpoint Register Block + +description: + The fsl_enetc driver can probe on the Integrated Endpoint Register Block, + which preconfigures the FIFO limits for the ENETC ports. + +maintainers: + - Frank Li <Frank.Li@xxxxxxx> + - Vladimir Oltean <vladimir.oltean@xxxxxxx> + - Wei Fang <wei.fang@xxxxxxx> + - Claudiu Manoil <claudiu.manoil@xxxxxxx> + +properties: + compatible: + enum: + - fsl,ls1028a-enetc-ierb + + reg: + maxItems: 1 + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + endpoint-config@f0800000 { + compatible = "fsl,ls1028a-enetc-ierb"; + reg = <0xf0800000 0x10000>; + }; diff --git a/Documentation/devicetree/bindings/net/fsl,enetc-mdio.yaml b/Documentation/devicetree/bindings/net/fsl,enetc-mdio.yaml new file mode 100644 index 0000000000000..c1dd6aa04321e --- /dev/null +++ b/Documentation/devicetree/bindings/net/fsl,enetc-mdio.yaml @@ -0,0 +1,57 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/fsl,enetc-mdio.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ENETC external MDIO PCIe endpoint device + +description: + NETC provides an external master MDIO interface (EMDIO) for managing external + devices (PHYs).
