+* IPQ806x DWMAC Ethernet controller
+
+The device inherits all the properties of the dwmac/stmmac devices
+described in the file net/stmmac.txt with the following changes.
+
+Required properties:
+
+- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
+ and any applicable more detailed version number
+ described in net/stmmac.txt
+
+- qcom,nss-common: should contain a phandle to a syscon device mapping the
+ nss-common registers.
+
+- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
+ qsgmii-csr registers.
+
+Example:
+
+ gmac: ethernet@37000000 {
+ device_type = "network";
+ compatible = "qcom,ipq806x-gmac";
+ reg = <0x37000000 0x200000>;
+ interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "macirq";
+
+ qcom,nss-common = <&nss_common>;
+ qcom,qsgmii-csr = <&qsgmii_csr>;
+
+ clocks = <&gcc GMAC_CORE1_CLK>;
+ clock-names = "stmmaceth";
+
+ resets = <&gcc GMAC_CORE1_RESET>;
+ reset-names = "stmmaceth";
+ };
