* 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-macb" 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-macb", 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>;
};
};
