   1 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.

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

  24 Example:
  25
  26         atmel-captouch@51 {
  27                 compatible = "atmel,captouch";
  28                 reg = <0x51>;
  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>,
  34                         <BTN_6>, <BTN_7>;
  35                 autorepeat;
