Don't we want to introduce a family-specific compatible value for
R-Car Gen4? At least the SCSS seems to be a new R-Car Gen4 feature
common to R-Car S4 and R-Car V3U (yes, the latter is advertised as
the first member of the R-Car Gen4 family, so I intend to move it
over to renesas,rcar-gen4-* where it makes sense).
