dt-bindings: net: sun7i-gmac: Convert the binding to a schemas 



Switch our Allwinner A20 GMAC controller binding to a YAML schema to enable
the DT validation. Since that controller is based on a Synopsys IP, let's
add the validation to that schemas with a bunch of conditionals.

* Allwinner GMAC ethernet controller



This device is a platform glue layer for stmmac.

Please see stmmac.txt for the other unchanged properties.



Required properties:

 - compatible:  Should be "allwinner,sun7i-a20-gmac"

 - clocks: Should contain the GMAC main clock, and tx clock

   The tx clock type should be "allwinner,sun7i-a20-gmac-clk"

 - clock-names: Should contain the clock names "stmmaceth",

   and "allwinner_gmac_tx"



Optional properties:

- phy-supply: phandle to a regulator if the PHY needs one



Examples:



	gmac: ethernet@1c50000 {

		compatible = "allwinner,sun7i-a20-gmac";

		reg = <0x01c50000 0x10000>,

		      <0x01c20164 0x4>;

		interrupts = <0 85 1>;

		interrupt-names = "macirq";

		clocks = <&ahb_gates 49>, <&gmac_tx>;

		clock-names = "stmmaceth", "allwinner_gmac_tx";

		phy-mode = "mii";

	};
