   2
   3 Required properties:
   4 - compatible: Must be one of
   5         "renesas,i2c-rcar"
   6         "renesas,i2c-r8a7778"
   7         "renesas,i2c-r8a7779"
   8         "renesas,i2c-r8a7790"
   9         "renesas,i2c-r8a7791"
  10         "renesas,i2c-r8a7792"
  11         "renesas,i2c-r8a7793"
  12         "renesas,i2c-r8a7794"
  13 - reg: physical base address of the controller and length of memory mapped
  14   region.
  15 - interrupts: interrupt specifier.
  16
  17 Optional properties:
  18 - clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
  19   propoerty indicates the default frequency 100 kHz.
  20 - clocks: clock specifier.

  24 i2c0: i2c@e6508000 {
  25         #address-cells = <1>;
  26         #size-cells = <0>;
