+* Oxford Semiconductor OXNAS DWMAC Ethernet controller
+
+The device inherits all the properties of the dwmac/stmmac devices
+described in the file stmmac.txt in the current directory with the
+following changes.
+
+Required properties on all platforms:
+
+- compatible: For the OX820 SoC, it should be :
+ - "oxsemi,ox820-dwmac" to select glue
+ - "snps,dwmac-3.512" to select IP version.
+
+- clocks: Should contain phandles to the following clocks
+- clock-names: Should contain the following:
+ - "stmmaceth" for the host clock - see stmmac.txt
+ - "gmac" for the peripheral gate clock
+
+- oxsemi,sys-ctrl: a phandle to the system controller syscon node
+
+Example :
+
+etha: ethernet@...00000 {
+ compatible = "oxsemi,ox820-dwmac", "snps,dwmac-3.512";
+ reg = <0x40400000 0x2000>;
+ interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "macirq", "eth_wake_irq";
+ mac-address = [000000000000]; /* Filled in by U-Boot */
+ phy-mode = "rgmii";
+
+ clocks = <&stdclk CLK_820_ETHA>, <&gmacclk>;
+ clock-names = "gmac", "stmmaceth";
+ resets = <&reset RESET_MAC>;
+
+ /* Regmap for sys registers */
+ oxsemi,sys-ctrl = <&sys>;
+
+ status = "disabled";
+};
