Or are they needed for backwards compatibility? The other compatible values in DT bindings and DTS files should be kept, to allow handling of SoC-specific quirks if/when they are ever detected. The other compatible values in the driver should be kept for backwards-compatibility with old DTB files that lack the (newer) family-specific compatible values.
