++* 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";
++	};
