    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.
