If for whatever reason a proposed "isp" label is preferred, then since a label rename is not an ABI change, it would make sense to do a massive change of renaming all camss labels. Otherwise there will be an outstanding incorrespondence/confusion of the label names in board .dts files, and that's bad. -- Best wishes, Vladimir
