| * 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) |
