Porting camera from tx1 to tx2


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,
