Yes, this is what I already wrote:

"How this should be fixed? First, drop bogus entries from drivers, then
document proper compatibles."

That's not really an answer... Bindings are correct because they are
correct? What is exactly correct in the bindings? How they reflect the
HW in a proper way, while DTS does not?

Or let's focus on actual hardware - what are the properties of the
hardware which indicate that DTS is wrong?
