OK, I guess that's why it's an RFC?
Yes. The latest clock/pcie driver did not work for me. I might have
missed something in DT.
The idea for RFC is so that anybody who wants to try the latest kernel
on a polarfire board
has a meaningful way to test it.

Looks like this one hasn't been merged yet. IDK if something is broken with my
mail client but I'm not seeing any github repos. If this depends on
not-yet-merged drivers then it's certainly RFC material, but aside from the DT
stuff (which should be straight-forward) it seems fine to me.
I think it makes sense to take this series once the clock driver is
merged at least.
Since you posted this an an RFC I'm going to assume you're going to re-spin it.
Yes. There are some feedbacks on DT which I will fix in v2.
Thanks!
Thanks!
