Subject[PATCH 2/2] dt-bindings: net: dwmac: document 'mac-mode' property
Date
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.

+ The property is identical to 'phy-mode', and assumes that there is mode
+ converter in-between the MAC & PHY (e.g. GMII-to-RGMII). This converter
+ can be passive (no SW requirement), and requires that the MAC operate
+ in a different mode than the PHY in order to function.
