See [1] for the full context. I'm\nactually aware of one user of this tuning file with a monochrome sensor,\nand this patch will break this use case.\n\nThis brings nack the question that we decided to leave unanswered when\nthe imx296.json file was merged: how do we deal with different modules\nthat integrated the same camera sensor ?\n\n[1] https://lists.libcamera.org/pipermail/libcamera-devel/2022-January/028756.html\n\n>

Our (admittedly very loose) convention\nis to have\nthe .json file be the full colour variant, and any offshoot be\nnamed as\n_.json. Would we be able to give a heads-up and help\nthis\nuser switch to imx296_mono.json? They would also benefit from the new\ntuning with\nupdated noise and sharpening IQ performance.\n\nThe difficult bit is how to choose a variant json without user\nintervention? Do we add\na variant parameter in devicetree? Some modules may have eeproms or ids\nthat can\nstore this, but I don't think there is a mechanism to return this\ninformation to userland\nfrom v4l2...?\n\nNaush\n\n\n>\n>\n> > Update the tuning file

There we have 2 compatible strings [1] as there isn't\na register to read for colour vs mono.\n\nThe driver has to know in order to advertise the correct MEDIA_BUS_FMT_ formats.\nDo we change the V4L2 sensor subdev name for variants (either based on\ncompatible or register) to denote an alternate tuning file? That\nshould then get magically picked up, but does it make for some\nconfusion choosing the camera helper?\n(It would be nice to have a convention, but as it will be down to the\ndriver to provide the name they could be switched around on a per\ndriver basis).\n\n Dave\n\n[1] https://github.com/raspberrypi/linux/blob/rpi-5.15.y/drivers/media/i2c/imx290.c#L1235\n\n> Naush\n>\n>>\n>>\n>>\n>> >

OV9281 and OV9282\napparently have differing CRA characteristics, so will potentially\nwant slightly different tunings should we wish to support both.\nAdding a nice way to use the compatible string or custom suffix would\nbe very useful.\n\n> Dave\n>\n> [1] https://github.com/raspberrypi/linux/blob/rpi-5.15.y/drivers/media/i2c/imx290.c#L1235\n>\n> > Naush\n> >\n> >>\n> >>\n> >>\n> >> > Update
