* Two Wire Serial Interface (TWSI) / I2C - compatible: "cavium,octeon-3860-twsi" Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs. or compatible: "cavium,octeon-7890-twsi" Compatibility with cn78XX 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>; }; };
