  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.
