Atmel maXTouch touchscreen/touchpad Required properties: - compatible: atmel,maxtouch - 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 . 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 = ; };
