I think pulled a series Dongchun Zhus earlier series apart and used some of it, I may have missed some of the feedback given to his v3.

Can you add a bit more general way of showing revision? This is modeled after the ov7251 driver, since that output came in handy during bringup. dev_info(dev, "OV7251 revision %x (%s) detected at address 0x%02x\n", chip_rev, chip_rev == 0x4 ? "1A / 1B" : chip_rev == 0x5 ? "1C / 1D" : chip_rev == 0x6 ? "1E" : chip_rev == 0x7 ? "1F" : "unknown", client->addr); To me this is pretty general approach, at least until this revision information is used in other places. I'm not quite sure what you had in mind. Maybe the current implementation is a little bit clunky in the case of ov8856 since there's only one revision number known currently. Either way, I'll happily change it. But I don't quite know what you have in mind. > > > + client->addr); > > -- > With Best Regards, > Andy Shevchenko > >
