Subject: [PATCH net-next 1/4] 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@...01000 {
- fixed-link {
- speed = <1000>;
- full-duplex;
- };
- };
-
- spi1: spi@...08000 {
- 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";
