/* 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.
