Comparing to RGMII interface, the RMII interface require few pins.
So it's worth describing them here.

The only axg platform we have upstream is the s400 and is using rgmii.
May I ask how this was tested ?

It's true that S400 using RGMII interface.
but, we have customer using RTL8201FR-VB/VD which is a RMII PHY,
This is actually tested with the 'eth_rmii_x_pins' group.

Applied to v4.17/dt64 with Neil's ack.
