  channel-mask:
    type: int
    description: Bitmask of enabled TSI channels (bit N = channel N)

  input-codes:
    type: array
    description: |
      Array of input codes corresponding to each enabled channels.
      Use INPUT_KEY_* or INPUT_BTN_* codes from dt-bindings/input/input-event-codes.h

  touch-threshold:
