Exactly, this is different. And it's not self-contained, which is
another requirement for staging code that we have learned to enforce
over the years (makes it easier to rip out if no one is willing to

I really do not understand the issue here, why can this just not be
Is the code somehow not ok? Is it relying on hardware in ways that
breaks other users? Does it cause problems for different users? Is it
a user api that you don't like or think is the "proper" one?
All staging drivers need a TODO list that shows what needs to be done in
order to get it out of staging. All I can tell so far is that the riscv
maintainers do not want to take this for "unknown reasons" so let's dump
it over here for now where we don't have to see it.
And that's not good for developers or users, so perhaps the riscv rules
are not very good?

What is this magical acceptance policy that is preventing working code
from being merged? And why is it suddenly the rest of the kernel
developer's problems because of this?
