Optional Properties:
- reset-gpios: Reference to the GPIO connected to the reset input.
+ - idle-state: if present, overrides i2c-mux-idle-disconnect,
+ Please refer to Documentation/devicetree/bindings/mux/mux-controller.txt
- i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
children in idle state. This is necessary for example, if there are several
multiplexers on the bus and the devices behind them use same I2C addresses.
