Device tree bindings for Atmel capacitive touch device, typically
|
|
an Atmel touch sensor connected to AtmegaXX MCU running firmware
|
|
based on Qtouch library.
|
|
|
|
The node for this device must be a child of a I2C controller node, as the
|
|
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.
|
|
|
|
Optional properties:
|
|
|
|
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>;
|
|
autorepeat;
|
|
};
