+ 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.
