Device tree bindings for Atmel capacitive touch device, typically
2
-
an Atmel touch sensor connected to AtmegaXX MCU running firmware
3
-
based on Qtouch library.
4
-
5
-
The node for this device must be a child of a I2C controller node, as the
6
-
device communicates via I2C.
7
-
8
-
Required properties:
9
-
10
-
compatible: Must be "atmel,captouch".
11
-
reg: The I2C slave address of the device.
12
-
interrupts: Property describing the interrupt line the device
13
-
is connected to. The device only has one interrupt
14
-
source.
15
-
linux,keycodes: Specifies an array of numeric keycode values to
16
-
be used for reporting button presses. The array can
17
-
contain up to 8 entries.
18

19
-
Optional properties:
20

21
-
autorepeat: Enables the Linux input system's autorepeat
22
-
feature on the input device.
