+Qualcomm Ethernet ETHQOS device
+
+This device has following properties:
+
+Required properties:
+
+- compatible: Should be qcom,ethqos-qcs404"
+
+- 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
+
