Porting camera


We are using camera in L4T 28.1 with TX1, and we need to migrate it to L4T 28.1 of TX2.
It is very similar to imx274.

But when I try to check the difference between tx1 in tx2 in imx274 dtsi, I see a lot of changes !

And instead of only 2 device trees for imx274:

There are now 5 dtsi ! :


Do we need to use all of them ?

Thank you for any suggestion,
