It is not considered compatible with existing fallback bindings due to the documented absence of automatic transmission registers. These registers are currently not used by the driver and thus the provides the same behaviour for "renesas,iic-r8a77990" and "renesas,rcar-gen3-iic". The point of declaring incompatibility is to allow for automatic transmission register support to be added to "renesas,iic-r8a77990" and "renesas,rcar-gen3-iic" in future. This series is split into two patches, one to update documentation and another to update the driver. I have no objections to it being squashed into a single patch if that is the maintainer's wish.
