It's clear to me to use "djn,9a-3r063-1102b" in the driver now but what
about dts?

Currently here in v2 we have this:
compatible =3D "fairphone,fp4-hx83112a-djn", "himax,hx83112a";

Should this just become this?
compatible =3D "djn,9a-3r063-1102b";

Or e.g. this?
compatible =3D "djn,9a-3r063-1102b", "himax,hx83112a";

Or something else completely? Do we have some documentation / best
practises around this maybe?

Luca
