I'm ok with such strategy, provided that the new driver builds fine with
COMPILE_TEST without the need of the dtsi patch.

Please also notice that, if the driver uses MC, it has to wait for
the MC next gen support to be merged, and may need to be rebased, due
to a few changes at the MC internal APIs: one function got renamed
(the function that create links between two pads) and we're now using
lists for links (that will only affect the driver if it has its own
graph traversal routines).

Btw, I just got a Samsung TM1 device, with seems to be using an arm64
SoC. Is this driver providing support for its camera?

Regards,
Mauro.
