Is it based on another SoC design then? Most new SoCs are derived from
some other
one, so it makes sense to put it into the same family. E.g. the Apple
M1 takes bits from
both Exynos and PA-Semi SoCs but has more newly added components than
either one.

I would argue that if this SoC shares the pinctrl, clock, spi, adc,
and timer implementation
with Exynos, we should consider it part of the Exynos family,
regardless of what other
blocks may exist next to those.
