If I want to extend the yaml file to compatible more versions of the aspeed adc.
Would you suggest to add new files call aspeed,ast2600-adc.yaml or just append it
to the aspeed,ast2400-adc.yaml?
Thanks
Best Regards,

If 2600 is not backwards compatible with 2400, then probably a new schema file. Given you are adding new properties (which only apply to 2600?), then most likely a new schema file. Depends at which point there are too many conditional (if/then/else) schemas. Rob

It's a judgement call you need to make on when it is worth the new file. Note that doesn't have anything to do with splitting the driver. We have mulitple binding files for single drivers and for that matter multiple drivers for single binding files. If it is 'compatible' enough to not make the file to complex, then add to the existing ast2400 file without renaming. Jonathan > > Rob
