So this is actually a slower rate that I've faced in my previous life working for a silicon vendor ;-) And my experience is that the IPs were different between the SoCs indeed but: 1. Not all of them at the same time (so no extra compatible values for others). 2. When there was a change it required change in a driver as well (so adding a compatible value is not an issue). 3. The changes were *completely* unpredictable (so even comprehensive list of DT properties wouldn't help) To summarize, count this as another vote for using compatible rather then "universal & future-proof" set of properties. Unless there is a very good rationale for it (I'm sure such cases exist) Thanks!
