Now, thanks to .yaml conversation, we can catch them. So, I ,personally, do not see reasons for separate patch here and think it can be done as part of Patch 3.

Driver fails to probe when 'clock' and 'clock-names' properties are not populated in DT. But the binding documentation says these properties are optional. Fix this by making 'clock' and 'clock-names' properties as required.
