+* Cadence MACB/GEM Ethernet controller
+
+Required properties:
+- compatible: Should be "cdns,[<chip>-]{macb|gem}"
+ Use "cdns,at91rm9200-emac" Atmel at91rm9200 SoC.
+ Use "cdns,at91sam9260-macb" for Atmel at91sam9 SoCs.
+ Use "cdns,sam9x60-macb" for Microchip sam9x60 SoC.
+ Use "cdns,np4-macb" for NP4 SoC devices.
+ Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
+ Use "cdns,pc302-gem" for Picochip picoXcell pc302 and later devices based on
+ the Cadence GEM, or the generic form: "cdns,gem".
+ Use "atmel,sama5d2-gem" for the GEM IP (10/100) available on Atmel sama5d2 SoCs.
+ Use "atmel,sama5d3-macb" for the 10/100Mbit IP available on Atmel sama5d3 SoCs.
+ Use "atmel,sama5d3-gem" for the Gigabit IP available on Atmel sama5d3 SoCs.
+ Use "atmel,sama5d4-gem" for the GEM IP (10/100) available on Atmel sama5d4 SoCs.
+ Use "cdns,zynq-gem" Xilinx Zynq-7xxx SoC.
+ Use "cdns,zynqmp-gem" for Zynq Ultrascale+ MPSoC.
+ Use "sifive,fu540-c000-gem" for SiFive FU540-C000 SoC.
+ Or the generic form: "cdns,emac".
+- reg: Address and length of the register set for the device
+ For "sifive,fu540-c000-gem", second range is required to specify the
+ address and length of the registers for GEMGXL Management block.
+- interrupts: Should contain macb interrupt
+- phy-mode: See ethernet.txt file in the same directory.
+- clock-names: Tuple listing input clock names.
+ Required elements: 'pclk', 'hclk'
+ Optional elements: 'tx_clk'
+ Optional elements: 'rx_clk' applies to cdns,zynqmp-gem
+ Optional elements: 'tsu_clk'
+- clocks: Phandles to input clocks.
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+Optional properties for PHY child node:
+- reset-gpios : Should specify the gpio for phy reset
+- magic-packet : If present, indicates that the hardware supports waking
+ up via magic packet.
+- phy-handle : see ethernet.txt file in the same directory
+
+Examples:
+
+ macb0: ethernet@fffc4000 {
+ compatible = "cdns,at32ap7000-macb";
+ reg = <0xfffc4000 0x4000>;
+ interrupts = <21>;
+ phy-mode = "rmii";
+ local-mac-address = [3a 0e 03 04 05 06];
+ clock-names = "pclk", "hclk", "tx_clk";
+ clocks = <&clkc 30>, <&clkc 30>, <&clkc 13>;
+ ethernet-phy@1 {
+ reg = <0x1>;
+ reset-gpios = <&pioE 6 1>;
+ };
+ };
