Hi Pratyush,

Thank you for the patch.

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,

Ok. Though I'd mention that I am not 100% sure what the pll_ref clock is 
supposed to be. The original binding doesn't have a description either.
