   3 Required properties:
   4 - compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac"
   5         For backwards compatibility: "st,spear600-gmac" is also supported.
   6 - reg: Address and length of the register set for the device
   7 - interrupt-parent: Should be the phandle for the interrupt controller
   8   that services interrupts for this device
   9 - interrupts: Should contain the STMMAC interrupts
  10 - interrupt-names: Should contain the interrupt names "macirq"
  11   "eth_wake_irq" if this interrupt is supported in the "interrupts"
  12   property
  13 - phy-mode: String, operation mode of the PHY interface.
  14   Supported values are: "mii", "rmii", "gmii", "rgmii".
  15 - snps,phy-addr         phy address to connect to.
  16 - snps,reset-gpio       gpio number for phy reset.
  17 - snps,reset-active-low boolean flag to indicate if phy reset is active low.
  18 - snps,reset-delays-us  is triplet of delays
  19         The 1st cell is reset pre-delay in micro seconds.
  20         The 2nd cell is reset pulse in micro seconds.
  21         The 3rd cell is reset post-delay in micro seconds.
  22 - snps,pbl              Programmable Burst Length
  23 - snps,fixed-burst      Program the DMA to use the fixed burst mode
  24 - snps,mixed-burst      Program the DMA to use the mixed burst mode
  25 - snps,force_thresh_dma_mode    Force DMA to use the threshold mode for
  26                                 both tx and rx
  27 - snps,force_sf_dma_mode        Force DMA to use the Store and Forward
  28                                 mode for both tx and rx. This flag is
  29                                 ignored if force_thresh_dma_mode is set.

  31 Optional properties:
  32 - mac-address: 6 bytes, mac address
  33 - resets: Should contain a phandle to the STMMAC reset signal, if any
  34 - reset-names: Should contain the reset signal name "stmmaceth", if a
  35         reset phandle is given
