   6 The device node has following properties.
   7
   8 Required properties:
   9 - compatible:  Should be "st,stm32-dwmac" to select glue, and
  10                "snps,dwmac-3.50a" to select IP version.
  11 - clocks: Must contain a phandle for each entry in clock-names.
  12 - clock-names: Should be "stmmaceth" for the host clock.
  13                Should be "mac-clk-tx" for the MAC TX clock.
  14                Should be "mac-clk-rx" for the MAC RX clock.
  15 - st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
  16               encompases the glue register, and the offset of the control register.
