   6 Required properties:
   7 - compatible: "ti,davinci-dm6467-emac", "ti,am3517-emac" or
   8   "ti,dm816-emac"
   9 - reg: Offset and length of the register set for the device
  10 - ti,davinci-ctrl-reg-offset: offset to control register
  11 - ti,davinci-ctrl-mod-reg-offset: offset to control module register
  12 - ti,davinci-ctrl-ram-offset: offset to control module ram
  13 - ti,davinci-ctrl-ram-size: size of control module ram
  14 - interrupts: interrupt mapping for the davinci emac interrupts sources:
  15               4 sources: <Receive Threshold Interrupt
  16                           Receive Interrupt
  17                           Transmit Interrupt
  18                           Miscellaneous Interrupt>
  19
  20 Optional properties:
  21 - phy-handle: See ethernet.txt file in the same directory.
  22               If absent, davinci_emac driver defaults to 100/FULL.
  23 - nvmem-cells: phandle, reference to an nvmem node for the MAC address
  24 - nvmem-cell-names: string, should be "mac-address" if nvmem is to be used
  25 - ti,davinci-rmii-en: 1 byte, 1 means use RMII
  26 - ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM?
