| /* pxa3xx keypad platform specific parameters |
| * |
| * 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 |
| * |
| * pxa168 keypad platform specific parameter |
| * |
| * NOTE: |
| * clear_wakeup_event callback is a workaround required to clear the |
| * keypad interrupt. The keypad wake must be cleared in addition to |
| * reading the MI/DI bits in the KPC register. |
