Microchip KSZ Series Ethernet switches
==================================

Required properties:

- compatible: For external switch chips, compatible string must be exactly one
  of the following:
  - "microchip,ksz9477"
  - "microchip,ksz9897"

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 {
