NAME
       matrix_keypad_build_keymap - convert platform keymap into matrix keymap

SYNOPSIS
       void matrix_keypad_build_keymap(const struct matrix_keymap_data * keymap_data, unsigned int row_shift, unsigned short * keymap,
				       unsigned long * keybit);

ARGUMENTS
       keymap_data
	   keymap supplied by the platform code

       row_shift
	   number of bits to shift row value by to advance to the next line in the keymap

       keymap
	   expanded version of keymap that is suitable for use by matrix keyboad driver

       keybit
	   pointer to bitmap of keys supported by input device

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