| 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 Miao | 76cb44e | 2008-01-31 00:59:23 -0500 | [diff] [blame] | 25 | * |
| 26 | * 4. matrix key and direct key will use the same debounce_interval by |
| 27 | * default, which should be sufficient in most cases |
