| Common i2c bus multiplexer/switch properties. |
| An i2c bus multiplexer/switch will have several child busses that are |
| numbered uniquely in a device dependent manner. The nodes for an i2c bus |
| multiplexer/switch will have one child node for each child |
| Required properties for child nodes: |
| - reg : The sub-bus number. |
| Optional properties for child nodes: |
| - Other properties specific to the multiplexer/switch hardware. |
| - Child nodes conforming to i2c bus binding |
