Re: [PATCH 2/6] net: phy: maxio: parse and enable PHY clock from generic DT binding

The generic PHY DT binding features a clocks property, which describes
the clock input to the PHY. Typically this is a crystal oscillator, so
it works without software interaction. But some boards want to save some
pennies on that part, and let a clock fanout pin from the SoC provide this
clock signal. In this case the PHY probe routine needs to enable this
clock explicitly.

Look for a "clocks" property inside the PHY node and enable that clock,
if one is provided.

This allows boards with a SoC-driven PHY clock to use the PHY. Please
note that without the clock enabled, the PHY will not be detected on the
MDIO bus, so the PHY-ID needs to be explicitly named in the PHY
compatible string:
	compatible = "ethernet-phy-id7b74.4411";
