++* 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";
++ };
