I would agree, though there seem to be some disagreements about where
such platform specific drivers should be located. From an earlier
exchange I had with Vivien about this matter:

It looks like things are going back and forth a bit. If I were Vivien, I
would be a bit frustrated by now and be close to giving up (Vivien, I
really commend you for your patience).

Is there a written guideline or policy people can look and point to
if/when something like this comes up ? Otherwise we may have the
LED/GPIO/xxx maintainers point one way, the X86 maintainers point the
other way, and thus may have reached a complete deadlock.
