This change documents the 'mac-mode' property that was introduced in the
'stmmac' driver to support passive mode converters that can sit in-between
the MAC & PHY.

Is this an array because {min,max}Items is for arrays? It should be 
defined as a string with possible values.

As this property is the same as another, you can do this:

$ref: ethernet-controller.yaml#/properties/phy-connection-type

Unless only a small subset of those values are valid here, then you may 
want to list them here.
