|
an Atmel touch sensor connected to AtmegaXX MCU running firmware
|
|
based on Qtouch library.

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
|

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

|
Example:
|
|
|
|
atmel-captouch@51 {
|
|
compatible = "atmel,captouch";
|
|
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>,
|
|
<BTN_6>, <BTN_7>;
