  interrupts:
    maxItems: 1
    description: |
      Property describing the interrupt line the
      device's ALERT#/CM_IRQ# pin is connected to.
      The device only has one interrupt source.

  autorepeat:
    description: |
      Enables the Linux input system's autorepeat feature on the input device.

  linux,keycodes:
    minItems: 3
    maxItems: 8
    description: |
      Specifies an array of numeric keycode values to
      be used for the channels. If this property is
      omitted, KEY_A, KEY_B, etc are used as defaults.
      The number of entries must correspond to the number of channels.

  microchip,sensor-gain:
    $ref: /schemas/types.yaml#/definitions/uint32
    default: 1
    enum: [1, 2, 4, 8]
    description: |
      Defines the gain of the sensor circuitry. This
      effectively controls the sensitivity, as a
      smaller delta capacitance is required to
      generate the same delta count values.

  microchip,irq-active-high:
    type: boolean
    description: |
      By default the interrupt pin is active low
      open drain. This property allows using the active
