356 * this table translates what's is in the AB8500 specification regarding the
357 * balls alternate functions (as for DB, default, ALT_A, ALT_B and ALT_C).
358 * ALTERNATE_FUNCTIONS(GPIO_NUMBER, GPIOSEL bit, ALTERNATFUNC bit1,
359 * ALTERNATEFUNC bit2, ALTA val, ALTB val, ALTC val),
360 *
361 * example :
362 *
363 * ALTERNATE_FUNCTIONS(13, 4, 3, 4, 0, 1 ,2),
364 * means that pin AB8500_PIN_W17 (pin 13) supports 4 mux (default/ALT_A,
365 * ALT_B and ALT_C), so GPIOSEL and ALTERNATFUNC registers are used to
366 * select the mux. ALTA, ALTB and ALTC val indicates values to write in
367 * ALTERNATFUNC register. We need to specifies these values as SOC
368 * designers didn't apply the same logic on how to select mux in the
369 * ABx500 family.
370 *
371 * As this pins supports at least ALT_B mux, default mux is
372 * selected by writing 1 in GPIOSEL bit :
373 *
374 * | GPIOSEL bit=4 | alternatfunc bit2=4 | alternatfunc bit1=3
375 * default | 1 | 0 | 0
376 * alt_A | 0 | 0 | 0
377 * alt_B | 0 | 0 | 1
378 * alt_C | 0 | 1 | 0
379 *
380 * ALTERNATE_FUNCTIONS(8, 7, UNUSED, UNUSED),
381 * means that pin AB8500_PIN_W18 (pin 8) supports 2 mux, so only GPIOSEL
382 * register is used to select the mux. As this pins doesn't support at
383 * least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
384 *
385 * | GPIOSEL bit=7 | alternatfunc bit2= | alternatfunc bit1=
386 * default | 0 | 0 | 0
387 * alt_A | 1 | 0 | 0
