   3 Required properties:
   4 - compatible: Should be "cdns,[<chip>-]{macb|gem}"
   5   Use "cdns,at91rm9200-emac" Atmel at91rm9200 SoC.
   6   Use "cdns,at91sam9260-macb" for Atmel at91sam9 SoCs or the 10/100Mbit IP
   7   available on sama5d3 SoCs.
   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 "cdns,pc302-gem" for Picochip picoXcell pc302 and later devices based on
  11   the Cadence GEM, or the generic form: "cdns,gem".
  12   Use "atmel,sama5d2-gem" for the GEM IP (10/100) available on Atmel sama5d2 SoCs.
  13   Use "atmel,sama5d3-gem" for the Gigabit IP available on Atmel sama5d3 SoCs.
  14   Use "atmel,sama5d4-gem" for the GEM IP (10/100) available on Atmel sama5d4 SoCs.
  15   Use "cdns,zynq-gem" Xilinx Zynq-7xxx SoC.

  17   Or the generic form: "cdns,emac".
  18 - reg: Address and length of the register set for the device
  19 - interrupts: Should contain macb interrupt
  20 - phy-mode: See ethernet.txt file in the same directory.
  21 - clock-names: Tuple listing input clock names.
  22         Required elements: 'pclk', 'hclk'
  23         Optional elements: 'tx_clk'
  24         Optional elements: 'rx_clk' applies to cdns,zynqmp-gem
  25 - clocks: Phandles to input clocks.
  26
  27 Optional properties for PHY child node:
  28 - reset-gpios : Should specify the gpio for phy reset
  29 - magic-packet : If present, indicates that the hardware supports waking
  30   up via magic packet.
