* Qualcomm Atheros QCA8xxx switch family
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible: should be one of:
|
||
|
|
"qca,qca8334"
|
||
|
|
"qca,qca8337"
|
||
|
|
|
||
|
|
- #size-cells: must be 0
|
||
|
|
- #address-cells: must be 1
|
||
|
|
|
||
|
|
Subnodes:
|
||
|
|
|
||
|
|
The integrated switch subnode should be specified according to the binding
|
||
|
|
described in dsa/dsa.txt. As the QCA8K switches do not have a N:N mapping of
|
||
|
|
port and PHY id, each subnode describing a port needs to have a valid phandle
|
||
|
|
referencing the internal PHY connected to it. The CPU port of this switch is
|
||
|
|
always port 0.
|
||
|
|
|
||
|
|
A CPU port node has the following optional node:
|
||
|
|
|
||
|
|
- fixed-link : Fixed-link subnode describing a link to a non-MDIO
|
||
|
|
managed entity. See
|
||
|
|
Documentation/devicetree/bindings/net/fixed-link.txt
|
||
|
|
for details.
|
||
|
|
|
||
|
|
For QCA8K the 'fixed-link' sub-node supports only the following properties:
|
||
|
|
|
||
|
|
- 'speed' (integer, mandatory), to indicate the link speed. Accepted
|
||
|
|
values are 10, 100 and 1000
|
||
|
|
- 'full-duplex' (boolean, optional), to indicate that full duplex is
|
||
|
|
used. When absent, half duplex is assumed.
|
||
|
|
|
||
|
|
