As I mentioned earlier, the LINFlexD clocks are not managed by Linux on this platform. They, along with several other clocks, are usually initialized by U‑Boot, and Linux does not handle them. That is likely the reason they were omitted from the S32V234 binding. I’m willing to correct this for the S32V234 compatible by making that property optional, so we don’t break compatibility. For S32G, I would prefer to avoid repeating the same oversight we had on S32V234 and make the property required, since the IP, as you correctly pointed out, does have dedicated clock inputs. How would you approach this?
