Kernel-3.10.0-957.el7_i2c-octeon

  • Two Wire Serial Interface (TWSI) / I2C
  • compatible: “cavium,octeon-3860-twsi”

    Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs.

  • reg: The base address of the TWSI/I2C bus controller register bank.

  • #address-cells: Must be <1>.

  • #size-cells: Must be <0>. I2C addresses have no size component.

  • interrupts: A single interrupt specifier.

  • clock-frequency: The I2C bus clock rate in Hz.

Example:
twsi0: i2c@1180000001000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = “cavium,octeon-3860-twsi”;
reg = <0x11800 0x00001000 0x0 0x200>;
interrupts = <0 45>;
clock-frequency = <100000>;

    rtc@68 {
        compatible = "dallas,ds1337";
        reg = <0x68>;
    };
    tmp@4c {
        compatible = "ti,tmp421";
        reg = <0x4c>;
    };
