+* 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";
 | 
						|
+	};
