   1Device tree bindings for Atmel capacitive touch device, typically
   2an Atmel touch sensor connected to AtmegaXX MCU running firmware
   3based on Qtouch library.
   4
   5The node for this device must be a child of a I2C controller node, as the
   6device communicates via I2C.
   7
   8Required 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.

  19Optional properties:
  20
  21        autorepeat:     Enables the Linux input system's autorepeat
  22                        feature on the input device.

  26        atmel-captouch@51 {
  27                compatible = "atmel,captouch";

  29                interrupt-parent = <&tlmm>;
  30                interrupts = <67 IRQ_TYPE_EDGE_FALLING>;
  31                linux,keycodes = <BTN_0>, <BTN_1>,
  32                        <BTN_2>, <BTN_3>,
  33                        <BTN_4>, <BTN_5>,
