You can drop the description.

It's best to describe individual items, which will then allow dropping
the maxItems property:
clocks:
items:
- description: Description of the psm clock
- description: Description of the pll_ref clock

This is copied verbatim from the existing description, but while at it,
I'd rename the node from dphy@... to phy@..., as DT node are supposed to
be named according to the class of devices, not the specific device
type.
With these small issues addressed,
