The bindings try to describe it. They are pretty often incomplete or
might have mistakes. The true reason of doing a change is not that some
tool tells you "do like this". The true reason is because the change
properly describes hardware.

This is just a tool, not an authority.

Because doing things "just because bindings told me" hides the true
explanation and makes the code review, code management more difficult.
Later person will look at this and wonder why this was done like this.
If you write "because some tool me" this is not a good help. But if you
write "because hardware is like this exactly" this is proper comment.

Again, don't focus on the tool... Tool is just a tool...
