I believe the rb3gen2 can be sold with and without the camera mezzanine
[1], so the approach we have taken for a similar situation on rb5 was to
have a separate mezzanine dts which includes the baseboard and extends it.

Please replicate that model here.

once you move this into its own dts the camera should be enabled by

You're enabling cci0 here but not the sensor for it - presumably a
monochrome sensor attached to one of the other CSIPHYs.
Zap cci0 here until you add that other sensor.

The commit log says imx577 but the comapt string says imx412.
Choose which one and maintain the namespace. Its an imx577 right ?
Upstream kernel has the relevant compat string
Commit: 1251663220d9 ("media: i2c: imx412: Add new compatible strings")
You can just cherry-pick that commit to your kernel and then the
upstream dts and downstream dts will be compatible.

This looks funny - why do you have MCLK2 ?
One final thing, you appear to be missing some power rails here no ?
e.g. rb5
vdda-phy-supply = <&vreg_l5a_0p88>;
vdda-pll-supply = <&vreg_l9a_1p2>;
