moderated list:ARM PORT, open list
Now that we have a proper binding for Ethernet switches hanging off
different buses, and a driver for the BCM53125 switch, add its Device
Tree as a child MDIO node, at MDIO address 30 (Broadcom pseudo-PHY
address) and describe the ports layout of the Lamobo R1 board.
This switch is hanging off the GMAC MDIO controller, not the
allwinner,sun4i-a10-mdio MDIO controller which is labeled "mdio"

Changes in v2:
- change the unit specifier to use hexadecimal
- name the GMAC MDIO controller label "mdio-gmac"
- specify board name in subject
Maxime,
You can find the B53 driver and its binding here:
