Yes, the diff says that already. Perhaps some explanation why you are
adding another vendor SoC to Samsung UART and how the h/w is
different. I can only guess based on having just gone thru this with
Apple.

The IP has been customized for the ARTPEC-8 SoC but is closely related
to the variants used on the Exynos chips.  I can add this information to
the commit message.

The choice of the vendor prefix is similar to the solution chosen in
this patch:
