Eric Miao62059d92008-01-31 00:59:03 -0500[diff] [blame]9/* pxa3xx keypad platform specific parameters
10 *
11 * NOTE:
12 * 1. direct_key_num indicates the number of keys in the direct keypad
13 * _plus_ the number of rotary-encoder sensor inputs, this can be
14 * left as 0 if only rotary encoders are enabled, the driver will
15 * automatically calculate this
16 *
17 * 2. direct_key_map is the key code map for the direct keys, if rotary
18 * encoder(s) are enabled, direct key 0/1(2/3) will be ignored
19 *
20 * 3. rotary can be either interpreted as a relative input event (e.g.
21 * REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
Eric Miao76cb44e2008-01-31 00:59:23 -0500[diff] [blame]22 *
23 * 4. matrix key and direct key will use the same debounce_interval by
24 * default, which should be sufficient in most cases
