Subject: [PATCH v2 1/1] dt-bindings: net: convert enetc to yaml
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.
- Remove fixed-link part.
Signed-off-by: Frank Li <Frank.Li@....com>
---
Change from v1 to v2
- renamee file as fsl,enetc-mdio.yaml, fsl,enetc-ierb.yaml, fsl,enetc.yaml
- example include pcie node

-* ENETC ethernet device tree bindings
-
-Depending on board design and ENETC port type (internal or
-external) there are two supported link modes specified by
-below device tree bindings.
-
-Required properties:
-
-- reg : Specifies PCIe Device Number and Function
- Number of the ENETC endpoint device, according
- to parent node bindings.
-- compatible : Should be "fsl,enetc".
-
-1. The ENETC external port is connected to a MDIO configurable phy
-
-1.1. Using the local ENETC Port MDIO interface
-
-In this case, the ENETC node should include a "mdio" sub-node
-that in turn should contain the "ethernet-phy" node describing the
-external phy. Below properties are required, their bindings
-already defined in Documentation/devicetree/bindings/net/ethernet.txt or
-Documentation/devicetree/bindings/net/phy.txt.
-
-Required:
-
-- phy-handle : Phandle to a PHY on the MDIO bus.
- Defined in ethernet.txt.
-
-- phy-connection-type : Defined in ethernet.txt.
-
-- mdio : "mdio" node, defined in mdio.txt.
-
-- ethernet-phy : "ethernet-phy" node, defined in phy.txt.
-
-Example:
-
- ethernet@0,0 {
- compatible = "fsl,enetc";
- reg = <0x000000 0 0 0 0>;
- phy-handle = <&sgmii_phy0>;
- phy-connection-type = "sgmii";
-
- mdio {
- #address-cells = <1>;
- #size-cells = <0>;
- sgmii_phy0: ethernet-phy@2 {
- reg = <0x2>;
- };
- };
- };
-
-1.2. Using the central MDIO PCIe endpoint device
-
-In this case, the mdio node should be defined as another PCIe
-endpoint node, at the same level with the ENETC port nodes.
-
-Required properties:
-
-- reg : Specifies PCIe Device Number and Function
- Number of the ENETC endpoint device, according
- to parent node bindings.
-- compatible : Should be "fsl,enetc-mdio".
-
-The remaining required mdio bus properties are standard, their bindings
-already defined in Documentation/devicetree/bindings/net/mdio.txt.
-
-Example:
-
- ethernet@0,0 {
- compatible = "fsl,enetc";
- reg = <0x000000 0 0 0 0>;
- phy-handle = <&sgmii_phy0>;
- phy-connection-type = "sgmii";
- };
-
- mdio@0,3 {
- compatible = "fsl,enetc-mdio";
- reg = <0x000300 0 0 0 0>;
- #address-cells = <1>;
- #size-cells = <0>;
- sgmii_phy0: ethernet-phy@2 {
- reg = <0x2>;
- };
- };
-
-2. The ENETC port is an internal port or has a fixed-link external
-connection
-
-In this case, the ENETC port node defines a fixed link connection,
-as specified by Documentation/devicetree/bindings/net/fixed-link.txt.
-
-Required:
-
-- fixed-link : "fixed-link" node, defined in "fixed-link.txt".
-
-Example:
- ethernet@0,2 {
- compatible = "fsl,enetc";
- reg = <0x000200 0 0 0 0>;
- fixed-link {
- speed = <1000>;
- full-duplex;
- };
- };
-
-* Integrated Endpoint Register Block bindings
-
-Optionally, the fsl_enetc driver can probe on the Integrated Endpoint Register
-Block, which preconfigures the FIFO limits for the ENETC ports. This is a node
-with the following properties:
-
-- reg : Specifies the address in the SoC memory space.
-- compatible : Must be "fsl,ls1028a-enetc-ierb".
-
-Example:
- ierb@...800000 {
- compatible = "fsl,ls1028a-enetc-ierb";
- reg = <0x01 0xf0800000 0x0 0x10000>;
- };
