[PATCH net-next v2 1/2] dt-bindings: net: qca,qca808x: Add regulator properties

[Alex Elder]

From: Daniel Thompson <daniel@xxxxxxxxxxxx>

QCA808x has four different power rails (although in many board designs
the different rails share a regulator). Add each of these to the
corresponding DT binding as optional supplies.
