OK. Then

Acked-by: Chen-Yu Tsai <wens@csie.org>

On the topic of having the class in the node name, I'm not aware of
any rules governing it. It feels like I made it up along the way.
I'm not even sure if it is supposed to be context-specific, like
if the node is the pin controller, then all child nodes would be
pin mux settings, and don't need to have "pins" in their names.

So I'm not so sure about this anymore. Feel free to ignore these
types of comments. :)
