+MediaTek DWMAC glue layer controller
+
+This file documents platform glue layer for stmmac.
+Please see stmmac.txt for the other unchanged properties.
+
+The device node has following properties.
+
+Required properties:
+- compatible: Should be "mediatek,mt2712-gmac" for MT2712 SoC
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the MAC interrupts
+- interrupt-names: Should contain a list of interrupt names corresponding to
+ the interrupts in the interrupts property, if available.
+ Should be "macirq" for the main MAC IRQ
+- clocks: Must contain a phandle for each entry in clock-names.
+- clock-names: the name of the clock listed in the clocks property. These are
+ "axi", "apb", "mac_ext", "mac_parent", "ptp_ref", "ptp_parent", "ptp_top"
+ for MT2712 SoC
+- mac-address: See ethernet.txt in the same directory
+- phy-mode: See ethernet.txt in the same directory
+
+Example:
+
+ eth: ethernet@1101c000 {
+ compatible = "mediatek,mt2712-gmac";
+ reg = <0 0x1101c000 0 0x1300>;
+ interrupts = <GIC_SPI 237 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-names = "macirq";
+ phy-mode ="rgmii-id";
+ mac-address = [00 55 7b b5 7d f7];
+ clock-names = "axi",
+ "apb",
+ "mac_ext",
+ "mac_parent",
+ "ptp_ref",
+ "ptp_parent",
+ "ptp_top";
+ clocks = <&pericfg CLK_PERI_GMAC>,
+ <&pericfg CLK_PERI_GMAC_PCLK>,
+ <&topckgen CLK_TOP_ETHER_125M_SEL>,
+ <&topckgen CLK_TOP_ETHERPLL_125M>,
+ <&topckgen CLK_TOP_ETHER_50M_SEL>,
+ <&topckgen CLK_TOP_APLL1_D3>,
+ <&topckgen CLK_TOP_APLL1>;
+ snps,txpbl = <32>;
+ snps,rxpbl = <32>;
+ snps,reset-gpio = <&pio 87 GPIO_ACTIVE_LOW>;
+ snps,reset-active-low;
+ };
