+Qualcomm Ethernet ETHQOS device
+
+This documents dwmmac based ethernet device which supports Gigabit
+ethernet for version v2.3.0 onwards.
+
+This device has following properties:
+
+Required properties:
+
+- compatible: Should be qcom,qcs404-ethqos"
+
+- reg: Address and length of the register set for the device
+
+- reg-names: Should contain register names "stmmaceth", "rgmii"
+
+- clocks: Should contain phandle to clocks
+
+- clock-names: Should contain clock names "stmmaceth", "pclk",
+ "ptp_ref", "rgmii"
+
+- interrupts: Should contain phandle to interrupts
+
+- interrupt-names: Should contain interrupt names "macirq", "eth_lpi"
+
+Rest of the properties are defined in stmmac.txt file in same directory
+
+
+Example:
+
+ethernet: ethernet@...0000 {
+ compatible = "qcom,qcs404-ethqos";
+ reg = <0x07a80000 0x10000>,
+ <0x07a96000 0x100>;
+ reg-names = "stmmaceth", "rgmii";
+ clock-names = "stmmaceth", "pclk", "ptp_ref", "rgmii";
+ clocks = <&gcc GCC_ETH_AXI_CLK>,
+ <&gcc GCC_ETH_SLAVE_AHB_CLK>,
+ <&gcc GCC_ETH_PTP_CLK>,
+ <&gcc GCC_ETH_RGMII_CLK>;
+ interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "macirq", "eth_lpi";
+ snps,reset-gpio = <&tlmm 60 GPIO_ACTIVE_LOW>;
+ snps,reset-active-low;
+
+ snps,txpbl = <8>;
+ snps,rxpbl = <2>;
+ snps,aal;
+ snps,tso;
+
+ phy-handle = <&phy1>;
+ phy-mode = "rgmii";
+
+ mdio {
+ #address-cells = <0x1>;
+ #size-cells = <0x0>;
+ compatible = "snps,dwmac-mdio";
+ phy1: phy@4 {
+ device_type = "ethernet-phy";
+ reg = <0x4>;
+ };
+ };
