^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5)   - compatible: Must contain one of the following.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6)     "lltc,ltc4305", "lltc,ltc4306"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7)   - reg: The I2C address of the device.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9)   The following required properties are defined externally:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)   - Standard I2C mux properties. See i2c-mux.txt in this directory.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12)   - I2C child bus nodes. See i2c-mux.txt in this directory.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) Optional Properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)   - enable-gpios: Reference to the GPIO connected to the enable input.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)   - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)     children in idle state. This is necessary for example, if there are several
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)     multiplexers on the bus and the devices behind them use same I2C addresses.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)   - gpio-controller: Marks the device node as a GPIO Controller.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)   - #gpio-cells: Should be two.  The first cell is the pin number and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 	the second cell is used to specify flags.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 	See ../gpio/gpio.txt for more information.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)   - ltc,downstream-accelerators-enable: Enables the rise time accelerators
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 	on the downstream port.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)   - ltc,upstream-accelerators-enable: Enables the rise time accelerators
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 	on the upstream port.
