     13/* pxa3xx keypad platform specific parameters
     14 *
     15 * NOTE:
     16 * 1. direct_key_num indicates the number of keys in the direct keypad
     17 *    _plus_ the number of rotary-encoder sensor inputs,  this can be
     18 *    left as 0 if only rotary encoders are enabled,  the driver will
     19 *    automatically calculate this
     20 *
     21 * 2. direct_key_map is the key code map for the direct keys, if rotary
     22 *    encoder(s) are enabled, direct key 0/1(2/3) will be ignored
     23 *
     24 * 3. rotary can be either interpreted as a relative input event (e.g.
     25 *    REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
     26 *
     27 * 4. matrix key and direct key will use the same debounce_interval by
     28 *    default, which should be sufficient in most cases
     29 *
     30 * pxa168 keypad platform specific parameter
     31 *
     32 * NOTE:
     33 * clear_wakeup_event callback is a workaround required to clear the
     34 * keypad interrupt. The keypad wake must be cleared in addition to
     35 * reading the MI/DI bits in the KPC register.
