[PATCH 1/2] dt-bindings: phy: qcom,usb-snps-femto-v2: Add REFGEN regulator

[Konrad Dybcio]

The HSPHY is (or at least can be) one of the users of the reference
voltage generating regulator. Ensure that dependency is described
properly.

My OCD isn't keen on the inconsistent full stop usage but that's a
nitpick of the context, not of the patch itself.

Supply names are local to the device (sink name), but this seems to be 
named based on the supply source. Maybe hard to do if all internal 
stuff. What is this supplying and what's the source if not REFGEN?

I don't think I have anything that would answer this question..
Though I would not at all be surprised if Qualcomm also called the
input "refgen"..

Maybe Bjorn or Dmitry would know.
