  * example :
  *
  *	ALTERNATE_FUNCTIONS(13,     4,      3,      4, 1, 0, 2),
  *	means that pin AB8505_PIN_D18 (pin 13) supports 4 mux (default/ALT_A,
  *	ALT_B and ALT_C), so GPIOSEL and ALTERNATFUNC registers are used to
  *	select the mux. ALTA, ALTB and ALTC val indicates values to write in
  *	ALTERNATFUNC register. We need to specifies these values as SOC
  *	designers didn't apply the same logic on how to select mux in the
  *	ABx500 family.
  *
  *	As this pins supports at least ALT_B mux, default mux is
  *	selected by writing 1 in GPIOSEL bit :
  *
  *		| GPIOSEL bit=4 | alternatfunc bit2=4 | alternatfunc bit1=3
  *	default	|       1       |          0          |          0

  *	alt_C	|       0       |          1          |          0
  *
  *	ALTERNATE_FUNCTIONS(1,      0, UNUSED, UNUSED),
  *	means that pin AB9540_PIN_R4 (pin 1) supports 2 mux, so only GPIOSEL
  *	register is used to select the mux. As this pins doesn't support at
  *	least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
  *
  *		| GPIOSEL bit=0 | alternatfunc bit2=  | alternatfunc bit1=
  *	default	|       0       |          0          |          0
