dt-bindings: net: dsa: convert ksz bindings document to yaml 



Convert the bindings document for Microchip KSZ Series Ethernet switches
from txt to yaml. Removed spi-cpha and spi-cpol flags is this should be
handled by the device driver.

Microchip KSZ Series Ethernet switches

==================================



Required properties:



- compatible: For external switch chips, compatible string must be exactly one

  of the following:

  - "microchip,ksz8765"

  - "microchip,ksz8794"

  - "microchip,ksz8795"

  - "microchip,ksz9477"

  - "microchip,ksz9897"

  - "microchip,ksz9896"

  - "microchip,ksz9567"

  - "microchip,ksz8565"

  - "microchip,ksz9893"

  - "microchip,ksz9563"

  - "microchip,ksz8563"



Optional properties:



- reset-gpios		: Should be a gpio specifier for a reset line

- microchip,synclko-125 : Set if the output SYNCLKO frequency should be set to

			  125MHz instead of 25MHz.



See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of additional

required and optional properties.



Examples:



Ethernet switch connected via SPI to the host, CPU port wired to eth0:



	eth0: ethernet@10001000 {

		fixed-link {

			speed = <1000>;

			full-duplex;

		};

	};



	spi1: spi@f8008000 {

		pinctrl-0 = <&pinctrl_spi_ksz>;

		cs-gpios = <&pioC 25 0>;

		id = <1>;



		ksz9477: ksz9477@0 {

			compatible = "microchip,ksz9477";

			reg = <0>;



			spi-max-frequency = <44000000>;

			spi-cpha;

			spi-cpol;



			ports {

				#address-cells = <1>;

				#size-cells = <0>;

				port@0 {

					reg = <0>;

					label = "lan1";

				};

				port@1 {

					reg = <1>;

					label = "lan2";

				};

				port@2 {

				};

				port@3 {

					label = "cpu";

					ethernet = <&eth0>;

					fixed-link {

						speed = <1000>;

						full-duplex;

					};

				};

			};

		};

			compatible = "microchip,ksz8565";

			reg = <0>;



			spi-max-frequency = <44000000>;

			spi-cpha;

			spi-cpol;

				port@0 {

					reg = <0>;

					label = "lan1";

				};

				port@1 {

					reg = <1>;

					label = "lan2";

				};

				port@2 {

					reg = <2>;

					label = "lan3";

				};

				port@3 {

					reg = <3>;

					label = "lan4";

				};

				port@6 {

					reg = <6>;

					label = "cpu";

					ethernet = <&eth0>;

					fixed-link {

						speed = <1000>;

						full-duplex;

					};

				};

			};

		};
