* 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@01c50000 {
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";
};
