description: |
|
|
Property describing the interrupt line the

device's ALERT#/CM_IRQ# pin is connected to.
|
|
The device only has one interrupt source.

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

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 array must have exactly six entries.

|
|
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
|
|
high push-pull output.
