3 - compatible: "cavium,octeon-3860-twsi"
4
5 Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs.
6
7 or
8
9 compatible: "cavium,octeon-7890-twsi"
10
11 Compatibility with cn78XX SOCs.
12
13 - reg: The base address of the TWSI/I2C bus controller register bank.
14
15 - #address-cells: Must be <1>.
16
17 - #size-cells: Must be <0>. I2C addresses have no size component.
18
19 - interrupts: A single interrupt specifier.
20
21 - clock-frequency: The I2C bus clock rate in Hz.

23 Example:
24 twsi0: i2c@1180000001000 {
25 #address-cells = <1>;
26 #size-cells = <0>;
27 compatible = "cavium,octeon-3860-twsi";
28 reg = <0x11800 0x00001000 0x0 0x200>;
29 interrupts = <0 45>;
