12 * 1. direct_key_num indicates the number of keys in the direct keypad
13 * _plus_ the number of rotary-encoder sensor inputs, this can be
14 * left as 0 if only rotary encoders are enabled, the driver will
15 * automatically calculate this
17 * 2. direct_key_map is the key code map for the direct keys, if rotary
18 * encoder(s) are enabled, direct key 0/1(2/3) will be ignored
20 * 3. rotary can be either interpreted as a relative input event (e.g.
21 * REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
