* 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 "atmel,sama5d2-gem" for the GEM IP (10/100) available on Atmel sama5d2 SoCs. |
|
Use "atmel,sama5d29-gem" for GEM XL IP (10/100) available on Atmel sama5d29 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. |
|
Use "microchip,sama7g5-emac" for Microchip SAMA7G5 ethernet interface. |
|
Use "microchip,sama7g5-gem" for Microchip SAMA7G5 gigabit ethernet interface. |
|
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 |
|
|
|
