- * Raw keyboard I/O layer for STM32
- *
- * To make this code portable, we rely heavily on looping over the keyboard
- * input and output entries in the board's gpio_list[]. Each set of inputs or
- * outputs must be listed in consecutive, increasing order so that scan loops
- * can iterate beginning at KB_IN00 or KB_OUT00 for however many GPIOs are
- * utilized (KEYBOARD_ROWS or KEYBOARD_COLS_MAX).
