By "in general", do you mean for the drivers code also?

As I have mentioned in the commit message for the driver, the other
device is very similar and if the support for it was ever to be added
(which I personally currently have no interest in), I believe it would
make sense to extend this driver. Is it then still prefered to call it
all just 88pm886 now?

So the file should be called marvell,88pm886-a1.yaml, correct? Again, is
it prefered to call it like this even if the other revision could
eventually be added (again, I am not interested in that right now
personally)? I mean, if I was implementing support for both revisions
right now, it would make sense to name it just marvell,88pm886.yaml, no?

Thank you, kind regards,
