By default the RB5 doesn't employ the navigation mezzanine. Thus I
suggest adding a new DTS file that will include the qrb5165-rb5.dts
and extend it with camcc/camss setup.
I remember, this was discussed back and forth. I think it's time we
either create a working repo for mezzanines or push default setups
into the kernel.
I'd vote for the later option.
