-Atmel maXTouch touchscreen/touchpad
-
-Required properties:
-- compatible:
- atmel,maxtouch
-
- The following compatibles have been used in various products but are
- deprecated:
- atmel,qt602240_ts
- atmel,atmel_mxt_ts
- atmel,atmel_mxt_tp
- atmel,mXT224
-
-- reg: The I2C address of the device
-
-- interrupts: The sink for the touchpad's IRQ output
- See ../interrupt-controller/interrupts.txt
-
-Optional properties for main touchpad device:
-
-- linux,gpio-keymap: When enabled, the SPT_GPIOPWN_T19 object sends messages
- on GPIO bit changes. An array of up to 8 entries can be provided
- indicating the Linux keycode mapped to each bit of the status byte,
- starting at the LSB. Linux keycodes are defined in
- <dt-bindings/input/input.h>.
-
- Note: the numbering of the GPIOs and the bit they start at varies between
- maXTouch devices. You must either refer to the documentation, or
- experiment to determine which bit corresponds to which input. Use
- KEY_RESERVED for unused padding values.
-
-- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)
-
-Example:
-
- touch@4b {
- compatible = "atmel,maxtouch";
- reg = <0x4b>;
- interrupt-parent = <&gpio>;
- interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
- };
