+* 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";
|
|
+ };
