360  * ALTERNATE_FUNCTIONS(GPIO_NUMBER, GPIOSEL bit, ALTERNATFUNC bit1,
361  * ALTERNATEFUNC bit2, ALTA val, ALTB val, ALTC val),

364  *
365  *	ALTERNATE_FUNCTIONS(13,     4,      3,      4, 0, 1 ,2),
366  *	means that pin AB8500_PIN_W17 (pin 13) supports 4 mux (default/ALT_A,
367  *	ALT_B and ALT_C), so GPIOSEL and ALTERNATFUNC registers are used to
368  *	select the mux.  ALTA, ALTB and ALTC val indicates values to write in
369  *	ALTERNATFUNC register. We need to specifies these values as SOC
370  *	designers didn't apply the same logic on how to select mux in the
371  *	ABx500 family.
372  *
373  *	As this pins supports at least ALT_B mux, default mux is
374  *	selected by writing 1 in GPIOSEL bit :
375  *
376  *		| GPIOSEL bit=4 | alternatfunc bit2=4 | alternatfunc bit1=3
377  *	default	|       1       |          0          |          0

379  *	alt_B	|       0       |          0          |          1
380  *	alt_C	|       0       |          1          |          0
381  *
382  *	ALTERNATE_FUNCTIONS(8,      7, UNUSED, UNUSED),
383  *	means that pin AB8500_PIN_W18 (pin 8) supports 2 mux, so only GPIOSEL
384  *	register is used to select the mux. As this pins doesn't support at
385  *	least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
386  *
387  *		| GPIOSEL bit=7 | alternatfunc bit2=  | alternatfunc bit1=
388  *	default	|       0       |          0          |          0
