   8   Use "cdns,np4-macb" for NP4 SoC devices.
   9   Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
  10   Use "atmel,sama5d2-gem" for the GEM IP (10/100) available on Atmel sama5d2 SoCs.
  11   Use "atmel,sama5d3-macb" for the 10/100Mbit IP available on Atmel sama5d3 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.

  18   Use "microchip,sama7g5-gem" for Microchip SAMA7G5 gigabit ethernet interface.
  19   Or the generic form: "cdns,emac".
  20 - reg: Address and length of the register set for the device
  21         For "sifive,fu540-c000-gem", second range is required to specify the
  22         address and length of the registers for GEMGXL Management block.
  23 - interrupts: Should contain macb interrupt
  24 - phy-mode: See ethernet.txt file in the same directory.
  25 - clock-names: Tuple listing input clock names.
  26         Required elements: 'pclk', 'hclk'
  27         Optional elements: 'tx_clk'
  28         Optional elements: 'rx_clk' applies to cdns,zynqmp-gem
  29         Optional elements: 'tsu_clk'
  30 - clocks: Phandles to input clocks.
  31
  32 The MAC address will be determined using the optional properties
  33 defined in ethernet.txt.
  34
  35 Optional properties for PHY child node:
  36 - reset-gpios : Should specify the gpio for phy reset
  37 - magic-packet : If present, indicates that the hardware supports waking
  38   up via magic packet.
  39 - phy-handle : see ethernet.txt file in the same directory
