| Common i2c arbitration bus properties. | |
| - i2c-arb child node | |
| Required properties for the i2c-arb child node: | |
| - #address-cells = <1>; | |
| - #size-cells = <0>; | |
| Optional properties for i2c-arb child node: | |
| - Child nodes conforming to i2c bus binding | |
| Example : | |
| /* | |
| An NXP pca9541 I2C bus master selector at address 0x74 | |
| with a NXP pca8574 GPIO expander attached. | |
