- * NOTE:
- * 1. direct_key_num indicates the number of keys in the direct keypad
- * _plus_ the number of rotary-encoder sensor inputs, this can be
- * left as 0 if only rotary encoders are enabled, the driver will
- * automatically calculate this
- *
- * 2. direct_key_map is the key code map for the direct keys, if rotary
- * encoder(s) are enabled, direct key 0/1(2/3) will be ignored
- *
- * 3. rotary can be either interpreted as a relative input event (e.g.
- * REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
- *
- * 4. matrix key and direct key will use the same debounce_interval by
- * default, which should be sufficient in most cases
