Subject[PATCH 3/3] Docs: dt: fsl-mc: update binding to define dpmac subnodes
Date
The fsl-mc node may optionally have dpmac sub-nodes that describe
the relationship between the Ethernet MACs which belong to the MC
and the Ethernet PHYs on the system board.

+ Definition: Specifies the id of the dpmac.

+ - phy-handle
+ Value type: <phandle>
+ Definition: Specifies the phandle to the PHY device node associated
