+ description: |
+ 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.
