SYNOPSIS

9       void
10                                       matrix_keypad_build_keymap(const struct matrix_keymap_data * keymap_data,
11                                       unsigned int row_shift,
12                                       unsigned short * keymap,
13                                       unsigned long * keybit);

ARGUMENTS

16       keymap_data
17           keymap supplied by the platform code
18
19       row_shift
20           number of bits to shift row value by to advance to the next line in
21           the keymap
22
23       keymap
24           expanded version of keymap that is suitable for use by matrix
25           keyboad driver
26
27       keybit
28           pointer to bitmap of keys supported by input device

DESCRIPTION

31       This function converts platform keymap (encoded with KEY macro) into an
32       array of keycodes that is suitable for using in a standard matrix
33       keyboard driver that uses row and col as indices.
