comments:
 - testing PWM is currently unclear; BSP also doesn't have PWM on Falcon
 - the idea was to use the GPIO logic analyzer with sniffing the GPIO input register
 - however, unlike other Gen3 SoCs the V3U doesn't allow GPIO sniffing by default
 - asking HW team if this can be achieved somehow

   - prototype patches made, only testing needed
   - seems not possible to test, marking abandoned
