^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)   The following required properties are defined externally:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)   - Standard I2C mux properties. See i2c-mux.txt in this directory.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)   - I2C child bus nodes. See i2c-mux.txt in this directory.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) Optional Properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27)   - reset-gpios: Reference to the GPIO connected to the reset input.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28)   - idle-state: if present, overrides i2c-mux-idle-disconnect,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29)     Please refer to Documentation/devicetree/bindings/mux/mux-controller.txt
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)   - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)     children in idle state. This is necessary for example, if there are several
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32)     multiplexers on the bus and the devices behind them use same I2C addresses.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33)   - interrupts: Interrupt mapping for IRQ.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)   - interrupt-controller: Marks the device node as an interrupt controller.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35)   - #interrupt-cells : Should be two.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36)     - first cell is the pin number
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37)     - second cell is used to specify flags.
