S32V also still used fsl prefix, despite the company name long being NXP
(same for several Layerscape and i.MX models).

If, as Radu indicated on 3/8, NXP wants to make that switch now for S32G
then I see no reason against nxp. I verified that it's already defined:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/vendor-prefixes.yaml

However, should the matching .dts[i] files using nxp prefix (4-6/8) then
still go under dts/freescale/, or should they go to a new dts/nxp/ then?
That would separate it from S32V. Intel did do a switch from dts/altera/
to dts/intel/ at some point, so there's precedence for either, I guess.
No idea whether anything might break if we moved S32V alongside S32G.

Similarly, the easiest and most merge-friendly would be to leave
arm/fsl.yaml and add the nxp-prefixed S32G2 there, as done here. If NXP
want to rename fsl.yaml to nxp.yaml in a general housekeeping effort,
that could be done independently, outside Chester's patchset.
