   1 Device tree configuration for i2c-ocores
   2
   3 Required properties:
   4 - compatible      : "opencores,i2c-ocores"
   5 - reg             : bus address start and address range size of device
   6 - interrupts      : interrupt number
   7 - clock-frequency : frequency of bus clock in Hz
   8 - #address-cells  : should be <1>
   9 - #size-cells     : should be <0>
  10
  11 Optional properties:
  12 - reg-shift       : device register offsets are shifted by this value
  13 - reg-io-width    : io register width in bytes (1, 2 or 4)
  14 - regstep         : deprecated, use reg-shift above

  16 Example:

  18         i2c0: ocores@a0000000 {
  19                 #address-cells = <1>;
  20                 #size-cells = <0>;
  21                 compatible = "opencores,i2c-ocores";
  22                 reg = <0xa0000000 0x8>;
  23                 interrupts = <10>;
  24                 clock-frequency = <20000000>;
  25
  26                 reg-shift = <0>;        /* 8 bit registers */
  27                 reg-io-width = <1>;     /* 8 bit read/write */
  28
  29                 dummy@60 {
  30                         compatible = "dummy";
  31                         reg = <0x60>;
  32                 };
