The patch looks good, except it would be more appropriate to move the
above properties to &clock_audss { }; node in this file.

Reviewed-by: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx>

As a side note, this is a dts patch and of course Kukjin maintains that.
You would likely get it applied sooner if you would have addressed it
directly to Kukjin, rather than Mark or me.
