The specific value of the phy-specifier shouldn't matter to this
binding. What should matter is what it logically corresponds to.

Could you define phys in terms of phy-names please? It makes the
relationship clearer:

- phys: a list of phandles + phy-sciefiers, one for each entry in
  phy-names

- phy-names: Should contain:
  * "sata-6g" for the SATA PHY <notes about requirements go here>

Cheers,
Mark.
