I tried this series on top of both 6.0-rc1 & next, but I saw a shed
load of errors from dtbs_check. I'll take a look at the rest of the
series later on, but just FYI. I know I have seen patches going into
different subsystems so I assume you're working on it. However, it
would be nice to let us what all the dependencies for this series are
dt-binding wise in the cover letter.
I have been trying to get riscv down to 0 warnings and would not be
in favour of accepting patches that go in the other direction.
(This patchset currently produces about 75 warnings)

Thanks,
Conor.
