An array of up to 8 entries can be provided 23*c66ec88fSEmmanuel Vadot indicating the Linux keycode mapped to each bit of the status byte, 24*c66ec88fSEmmanuel Vadot starting at the LSB. Linux keycodes are defined in 25*c66ec88fSEmmanuel Vadot <dt-bindings/input/input.h>. 26*c66ec88fSEmmanuel Vadot 27*c66ec88fSEmmanuel Vadot Note: the numbering of the GPIOs and the bit they start at varies between 28*c66ec88fSEmmanuel Vadot maXTouch devices. You must either refer to the documentation, or 29*c66ec88fSEmmanuel Vadot experiment to determine which bit corresponds to which input. Use 30*c66ec88fSEmmanuel Vadot KEY_RESERVED for unused padding values. 31*c66ec88fSEmmanuel Vadot 32*c66ec88fSEmmanuel Vadot- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low) 33*c66ec88fSEmmanuel Vadot 34*c66ec88fSEmmanuel VadotExample: 35*c66ec88fSEmmanuel Vadot 36*c66ec88fSEmmanuel Vadot touch@4b { 37*c66ec88fSEmmanuel Vadot compatible = "atmel,maxtouch"; 38*c66ec88fSEmmanuel Vadot reg = <0x4b>; 39*c66ec88fSEmmanuel Vadot interrupt-parent = <&gpio>; 40*c66ec88fSEmmanuel Vadot interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>; 41*c66ec88fSEmmanuel Vadot }; 42
