   1 Binding for the Cadence I2C controller
   2
   3 Required properties:
   4   - reg: Physical base address and size of the controller's register area.
   5   - compatible: Should contain one of:
   6                 * "cdns,i2c-r1p10"
   7                 Note:   Use this when cadence i2c controller version 1.0 is used.
   8                 * "cdns,i2c-r1p14"
   9                 Note:   Use this when cadence i2c controller version 1.4 is used.
  10   - clocks: Input clock specifier. Refer to common clock bindings.
  11   - interrupts: Interrupt specifier. Refer to interrupt bindings.
  12   - #address-cells: Should be 1.
  13   - #size-cells: Should be 0.
  14
  15 Optional properties:
  16   - clock-frequency: Desired operating frequency, in Hz, of the bus.
  17   - clock-names: Input clock name, should be 'pclk'.

  19 Example:
  20         i2c@e0004000 {
  21                 compatible = "cdns,i2c-r1p10";
  22                 clocks = <&clkc 38>;
  23                 interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
  24                 reg = <0xe0004000 0x1000>;
  25                 clock-frequency = <400000>;
  26                 #address-cells = <1>;
  27                 #size-cells = <0>;
  28         };
