I'd done a comparison of the datasheets, and register 0x3011 was the only one that changed. I'd missed that it was in imx290_global_init_settings. My datasheets: IMX327LQR-C rev E17Z06B93 2019/03/25. 3011h "Set to 02h" (value changed in doc rev 0.3 from 0Ah) IMX290LQR-C rev E15510G82 2018/02/09. 3011h "Fixed to 00h" (always been that value). IMX462LQR-C rev E19Y13C13 2021/03/19. 3011h "Set to 02h" (value changed in doc rev 0.2 from 00h) The default value stated in all of them is 00h. In true Sony fashion, there's no description for that register functionality. So actually it looks like it was the addition of IMX327 in [1] should have changed that setting, unless someone else has a more recent datasheet for IMX290 that updates that. cc Alexander as the author of that patch. I'll find any discussion on it later.

I agree with this analysis. It may be that setting the register to 0x02 would be fine, but it's hard to tell. Maybe it could be worth asking Sony ? > cc Alexander as the author of that patch.

I'll find any discussion on it later. I've looked back to find the earlier discussion. v3 at [1] was the version that was merged. This added register 0x3011 when previously it hadn't been set. I had picked up at v2[2] that register 0x3011 should have been in imx290_global_init_settings_327 rather than imx290_global_init_settings, but that appeared not to have happened. In my book that makes it a regression for imx290 due to that patch, and we should correct it back to 0x00. I could check with Sony over that, but it seems overkill seeing as we have deviated from the originally submitted driver in a way that contradicts the datasheet. I'll send a v2 patchset on that basis.

IMX462 is the successor to IMX290, and wants very minor changes to the register setup. Add the relevant configuration to support it.
