* this table translates what's is in the AB8505 specification regarding the

* ALTERNATE_FUNCTIONS(GPIO_NUMBER, GPIOSEL bit, ALTERNATFUNC bit1,
* ALTERNATEFUNC bit2, ALTA val, ALTB val, ALTC val),
*
* 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_A | 0 | 0 | 1
* alt_B | 0 | 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
* alt_A | 1 | 0 | 0
