Point taken. I was primarily concerned about needless churn during early
development. But given the latest discussions it has become clear that
there's no need to rush things and therefore we should be able to
resolve any potential issues that could result in churn before the first
patches are merged.

drivers/gpu/host1x sounds like a good location to me. Does that still go
in via your tree?
