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
- d9dbda2f774c38dd60f3b17b7e3dac11bb0e3a97, 73d8a0fb46ab4f822f953ad20e5fbdb5998352c1, 91284dd61b7c36fe536d8ad6c473bbc04b4328da
- prototype patches made, only testing needed
- seems not possible to test, marking abandoned
