I will not update/maintain this, just have the impression that here some
more work is needed to make somebody comfortable with yaml than stick
to the usual pointing to documentation and I have not the ingredients
for doing
cat  Antihistamines >/dev/brain ;-)
and I do not want to see the other patches get lost.
Looks about right...

My prior comment still applies.

Also, for a single clock, you don't really need a name.

'make dt_binding_check' would have pointed the error here for you:
