    1 Actions Semiconductor Owl I2C controller
    2 
    3 Required properties:
    4 
    5 - compatible        : Should be one of the following:
    6                       - "actions,s700-i2c" for S700 SoC
    7                       - "actions,s900-i2c" for S900 SoC
    8 - reg               : Offset and length of the register set for the device.
    9 - #address-cells    : Should be 1.
   10 - #size-cells       : Should be 0.
   11 - interrupts        : A single interrupt specifier.
   12 - clocks            : Phandle of the clock feeding the I2C controller.
   13 
   14 Optional properties:
   15 
   16 - clock-frequency   : Desired I2C bus clock frequency in Hz. As only Normal and
   17                       Fast modes are supported, possible values are 100000 and
   18                       400000.
   19 Examples:
   20 
   21         i2c0: i2c@e0170000 {
   22                 compatible = "actions,s900-i2c";
   23                 reg = <0 0xe0170000 0 0x1000>;
   24                 #address-cells = <1>;
   25                 #size-cells = <0>;
   26                 interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
   27                 clocks = <&clock CLK_I2C0>;
   28                 clock-frequency = <100000>;
   29         };
