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.
