* 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 or the 10/100Mbit IP
|
|
available on sama5d3 SoCs.
|
|
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-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.
|
|
Or the generic form: "cdns,emac".
|
|
- reg: Address and length of the register set for the device
|
|
- 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.
|
|
|
|
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-mode = "rmii";
|
|
local-mac-address = [3a 0e 03 04 05 06];
|
|
clock-names = "pclk", "hclk", "tx_clk";
