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 {
|
||
|
|
speed = <1000>;
|
||
|
|
full-duplex;
|
||
|
|
};
|
||
|
|
};
|
||
|
|
|
||
|
|
