Maybe it's just me, but I don't think this tone is necessary.

Wilken's original submission was correct. Later there was a comment just
on the binding patch, to remove the not needed clock-names and reset-names
properties. But there was not a word in there that the driver requires
changing as well, and I don't think it's fair to blame Wilken on this, or
somewhat even implying intention. There were several patch revisions after
this was raised, and this just slipped through review. But surely no one
wanted this or pushed for that.

If anything, it tells us that we should be more careful when merging
drivers without users: if there would have been a DT patch, possibly even
a consumer, this would have been flagged by dtbs_check.

Cheers,
