1 Atmel maXTouch touchscreen/touchpad
7 The following compatibles have been used in various products but are
14 - reg: The I2C address of the device
16 - interrupts: The sink for the touchpad's IRQ output
17 See ../interrupt-controller/interrupts.txt
19 Optional properties for main touchpad device:
21 - linux,gpio-keymap: When enabled, the SPT_GPIOPWN_T19 object sends messages
22 on GPIO bit changes. An array of up to 8 entries can be provided
23 indicating the Linux keycode mapped to each bit of the status byte,
24 starting at the LSB. Linux keycodes are defined in
25 <dt-bindings/input/input.h>.
27 Note: the numbering of the GPIOs and the bit they start at varies between
28 maXTouch devices. You must either refer to the documentation, or
29 experiment to determine which bit corresponds to which input. Use
30 KEY_RESERVED for unused padding values.
32 - reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)
37 compatible = "atmel,maxtouch";
39 interrupt-parent = <&gpio>;
40 interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
