7 - reg: The I2C address of the device.
11 - Standard I2C mux properties. See i2c-mux.yaml in this directory.
12 - I2C child bus nodes. See i2c-mux.yaml in this directory.
16 - enable-gpios: Reference to the GPIO connected to the enable input.
17 - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
18 children in idle state. This is necessary for example, if there are several
19 multiplexers on the bus and the devices behind them use same I2C addresses.

13 A multiplexer (or mux) controller will have one, or several, consumer devices
14 that uses the mux controller. Thus, a mux controller can possibly control
