No changes here. The review tag was conditional in a way that I assumed
you will implement this change.

Best regards,

Sorry I misunderstood your comment. I renamed the "clocks" node.
By the way, after a review, this nod is useless (not used).

The "clocks" node was okay, you can also remove it. I was commenting
below the clock itself. The device nodes should have generic names, so
"clock" or "clock-16m".
