|
The LAN9303 is a three port ethernet switch with integrated PHYs for the
|
|
two external ports. The third port is an RMII/MII interface to a host
|
|
processor. The device can be managed via I2C or MDIO.
|
|
|
|
Note - always use 'reg = <0/1/2>;' for the three DSA ports, even if the
|
|
device is configured to use 1/2/3 instead. This hardware configuration
|
|
will be auto-detected and mapped accordingly.
