0007 or
0008
0009 compatible: "cavium,octeon-7890-twsi"
0010
0011 Compatibility with cn78XX SOCs.
0012
0013 - reg: The base address of the TWSI/I2C bus controller register bank.
0014
0015 - #address-cells: Must be <1>.
0016
0017 - #size-cells: Must be <0>. I2C addresses have no size component.
0018
0019 - interrupts: A single interrupt specifier.
0020
0021 - clock-frequency: The I2C bus clock rate in Hz.
