|
|
device communicates via I2C.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
compatible: Must be "atmel,captouch".
|
||
|
|
reg: The I2C slave address of the device.
|
||
|
|
interrupts: Property describing the interrupt line the device
|
||
|
|
is connected to. The device only has one interrupt
|
||
|
|
source.
|
||
|
|
linux,keycodes: Specifies an array of numeric keycode values to
|
||
|
|
be used for reporting button presses. The array can
|
||
|
|
contain up to 8 entries.

atmel-captouch@51 {
|
||
|
|

|
||
|
|
reg = <0x51>;
|
||
|
|
interrupt-parent = <&tlmm>;
|
||
|
|
interrupts = <67 IRQ_TYPE_EDGE_FALLING>;
|
||
|
|
linux,keycodes = <BTN_0>, <BTN_1>,
|
||
|
|
<BTN_2>, <BTN_3>,
|
||
|
|
<BTN_4>, <BTN_5>,
