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 | |

371 | * ABx500 family. | |
372 | * | |
373 | * As this pins supports at least ALT_B mux, default mux is | |
