* Qualcomm Atheros QCA8xxx switch family

Required properties:

- compatible: should be one of:
    "qca,qca8334"
    "qca,qca8337"

- #size-cells: must be 0
- #address-cells: must be 1

Subnodes:

The integrated switch subnode should be specified according to the binding
described in dsa/dsa.txt. As the QCA8K switches do not have a N:N mapping of
port and PHY id, each subnode describing a port needs to have a valid phandle
referencing the internal PHY connected to it. The CPU port of this switch is
always port 0.

A CPU port node has the following optional node:

- fixed-link            : Fixed-link subnode describing a link to a non-MDIO
                          managed entity. See
                          Documentation/devicetree/bindings/net/fixed-link.txt
                          for details.

For QCA8K the 'fixed-link' sub-node supports only the following properties:

- 'speed' (integer, mandatory), to indicate the link speed. Accepted
  values are 10, 100 and 1000
- 'full-duplex' (boolean, optional), to indicate that full duplex is
  used. When absent, half duplex is assumed.

Example:


	&mdio0 {
		phy_port1: phy@0 {
			reg = <0>;
		};

		phy_port2: phy@1 {
			reg = <1>;
		};

		phy_port3: phy@2 {
			reg = <2>;
		};

		phy_port4: phy@3 {
			reg = <3>;
		};

		phy_port5: phy@4 {
			reg = <4>;
		};

		switch0@0 {
			compatible = "qca,qca8337";
			#address-cells = <1>;
			#size-cells = <0>;

			reg = <0>;

			ports {
				#address-cells = <1>;
				#size-cells = <0>;
				port@0 {
					reg = <0>;
					label = "cpu";
					ethernet = <&gmac1>;
					phy-mode = "rgmii";
					fixed-link {
						speed = 1000;
						full-duplex;
					};
				};

				port@1 {
					reg = <1>;
					label = "lan1";
					phy-handle = <&phy_port1>;
				};

				port@2 {
					reg = <2>;
					label = "lan2";
					phy-handle = <&phy_port2>;
				};

				port@3 {
					reg = <3>;
					label = "lan3";
					phy-handle = <&phy_port3>;
				};

				port@4 {
					reg = <4>;
					label = "lan4";
					phy-handle = <&phy_port4>;
				};

				port@5 {
					reg = <5>;
					label = "wan";
					phy-handle = <&phy_port5>;
				};
			};
		};
	};
