| 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>; |
