Full stop.

Subject: drop second, redundant "bindings for".

Drop "Device Driver"

Drop "Bindings for". Actually, either drop entire description or write
something else than title.

Drop description.

Drop description.

This should be fixed, not flexible. Why it's flexible?

lowercase letters only

Why this is a property of DT/hardware? Don't encode policy in DT.

Same question.

Same question - why this number differs with hardware?
