There are no in-kernel users of pxa27x_keypad_platform_data in the kernel, and the driver supports configuration via device tree, so drop support of static platform data and move properties parsing from OF-specific methods to generic ones.

| 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. | ||
