Aren't the clocks now required? Will it keep working without them?

There are not required, this just allows passing them but the driver is
still using global matching until in patch 2 XO and sleep clocks are converted
to use parent data and in patch 3 they are passed via phandles to GCC,
however, even then global matching by name is preserved in the driver
as a fallback
to keep backward compatibility.
However, I see your point, after parent data conversion they should be
required by
schema as that is preferred over global matching.
I will wait for some time for feedback on other patches and then send
v2 that includes
that change.

Robert
