  Guidelines for new compatibles for SoC blocks/components.
  When adding new compatibles in new bindings, use the format::
    renesas,SoC-IP

  For example::
   renesas,r8a77965-csi2

  When adding new compatibles to existing bindings, use the format in the
  existing binding, even if it contradicts the above.
