The reason for using Exynos8855 is that it comes from the chip-id register, which is RO register.
And in my opinion it has to be chip-id, maintaining two names is confusing (as you also mentioned).
Yes, there were couple of deviation but let's come back to the "original" convention (which is to use chip-id).

Any input on this?
