13 *
14 * NOTE:
15 * 1. direct_key_num indicates the number of keys in the direct keypad
16 * _plus_ the number of rotary-encoder sensor inputs, this can be
17 * left as 0 if only rotary encoders are enabled, the driver will
18 * automatically calculate this
19 *
20 * 2. direct_key_map is the key code map for the direct keys, if rotary
21 * encoder(s) are enabled, direct key 0/1(2/3) will be ignored
22 *
23 * 3. rotary can be either interpreted as a relative input event (e.g.
24 * REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
Eric Miao76cb44e2008-01-31 00:59:23 -050025 *
26 * 4. matrix key and direct key will use the same debounce_interval by
27 * default, which should be sufficient in most cases
