  1. * Cadence MACB/GEM Ethernet controller
  2. Required properties:
  3. - compatible: Should be "cdns,[<chip>-]{macb|gem}"
  4. Use "cdns,at91rm9200-emac" Atmel at91rm9200 SoC.
  5. Use "cdns,at91sam9260-macb" for Atmel at91sam9 SoCs or the 10/100Mbit IP
  6. available on sama5d3 SoCs.
  7. Use "cdns,np4-macb" for NP4 SoC devices.
  8. Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
  9. Use "cdns,pc302-gem" for Picochip picoXcell pc302 and later devices based on
  10. the Cadence GEM, or the generic form: "cdns,gem".
  11. Use "atmel,sama5d2-gem" for the GEM IP (10/100) available on Atmel sama5d2 SoCs.
  12. Use "atmel,sama5d3-gem" for the Gigabit IP available on Atmel sama5d3 SoCs.
  13. Use "atmel,sama5d4-gem" for the GEM IP (10/100) available on Atmel sama5d4 SoCs.
  14. Use "cdns,zynq-gem" Xilinx Zynq-7xxx SoC.
  15. Use "cdns,zynqmp-gem" for Zynq Ultrascale+ MPSoC.
  16. Or the generic form: "cdns,emac".
  17. - reg: Address and length of the register set for the device
  18. - interrupts: Should contain macb interrupt
  19. - phy-mode: See ethernet.txt file in the same directory.
  20. - clock-names: Tuple listing input clock names.
  21. Required elements: 'pclk', 'hclk'
  22. Optional elements: 'tx_clk'
  23. Optional elements: 'rx_clk' applies to cdns,zynqmp-gem
  24. - clocks: Phandles to input clocks.
  25. Optional properties for PHY child node:
  26. - reset-gpios : Should specify the gpio for phy reset
  27. - magic-packet : If present, indicates that the hardware supports waking
  28. up via magic packet.
  29. Examples:
  30. macb0: ethernet@fffc4000 {
  31. compatible = "cdns,at32ap7000-macb";
  32. reg = <0xfffc4000 0x4000>;
  33. interrupts = <21>;
  34. phy-mode = "rmii";
  35. local-mac-address = [3a 0e 03 04 05 06];
  36. clock-names = "pclk", "hclk", "tx_clk";
  37. clocks = <&clkc 30>, <&clkc 30>, <&clkc 13>;
  38. ethernet-phy@1 {
  39. reg = <0x1>;
  40. reset-gpios = <&pioE 6 1>;
  41. };
  42. };
