Seems pretty cool. This SOC is bound to have pretty good upstream linux support to, since the Snapdragon 660 is in very good shape.
The 662 is much newer (what a weird numbering scheme…) so there's probably many differences to the 660..
It seems to be a 11nm part as opposed to the 660 which is a 14nm part.
This all being said, it won't be plug & play with upstream linux today. But probably soon enough. This project likely is based on Qcom downstream kernels for the moment.
