I'm not sure how this isn't failing on the example because it is wrong.

You're saying this compatible belongs at the same level as 
phys/phy-names, but that would be the parent which already has a 
compatible. You have to define a child node property (gnss@4) and have 
'compatible' under it. At that point, this schema becomes very much 
Motorola specific.
