* 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>;
		};
	};
