    reset-gpios:
      type: phandle-array
      required: true
      description: RESET pin.

        The RESET pin of SSD16XX is active low.
        If connected directly the MCU pin should be configured
        as active low.

    dc-gpios:
      type: phandle-array
      required: true
      description: DC pin.

        The DC pin of SSD16XX is active low (transmission command byte).
        If connected directly the MCU pin should be configured
        as active low.

    busy-gpios:
      type: phandle-array
      required: true
      description: BUSY pin.

        The BUSY pin of SSD16XX is active high.
        If connected directly the MCU pin should be configured
        as active high.

    lut-initial:
      type: uint8-array
      description: |
        Initial LUT used when initializing the device and performing
        clearing the screen using a full refresh operation. The
        default LUT will be loaded from OTP if this property isn't
        defined.

    lut-default:
      type: uint8-array

    tssv:
      type: int
      description: Temperature Sensor Selection Value

        Display controller can have integrated temperature sensor or
        an external temperature sensor is connected to the controller.
        The value selects which sensor should be used.
