Subject[PATCH v2] ARM: dts: sun7i: Add BCM53125 switch nodes to the lamobo-r1 board
Date
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"

Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>

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:
