^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 	reg:			The I2C slave address of the device.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 	interrupts:		Property describing the interrupt line the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 				device's ALERT#/CM_IRQ# pin is connected to.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 				The device only has one interrupt source.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 	autorepeat:		Enables the Linux input system's autorepeat
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 				feature on the input device.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) 	microchip,sensor-gain:	Defines the gain of the sensor circuitry. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 				effectively controls the sensitivity, as a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 				smaller delta capacitance is required to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 				generate the same delta count values.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 				Valid values are 1, 2, 4, and 8.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) 				By default, a gain of 1 is set.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) 	microchip,irq-active-high:	By default the interrupt pin is active low
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) 				open drain. This property allows using the active
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 				high push-pull output.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 	linux,keycodes:		Specifies an array of numeric keycode values to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) 				be used for the channels. If this property is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 				omitted, KEY_A, KEY_B, etc are used as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 				defaults. The array must have exactly six
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 				entries.
