Hi,

this is mostly about the first patch, which moves the IPUv3 core code
(drivers/staging/imx-drm/ipu-v3) to drivers/gpu. host1x, which
serves a similar purpose, already sits there.
The other four patches add the necessary code for CSI and SMFC handling,
which is used by the V4L2 CSI capture driver.

Currently this is based on Russell's patch
    [PATCH 62/64] imx-drm: pass an IPU ID to crtc and core

I am aware that there are now quite a few other patches in the pipeline
that touch drivers/staging/imx-drm/ipu-v3/*, so I am happy to rebase this
(or them) as needed. I'd like to move the core code out of staging so that
we can start submitting V4L2 code for video capture and scaling / colorspace
conversion in parallel.

I'd recommend doing the move (if the gpu/drm maintainer agrees) after
3.14-rc1 as then all of my pending patches would be applied and we would
be synced up with everything.

Ok.

Once this "core" is moved, what is keeping the rest in staging and why
isn't it moving out as well?

Russell put a lot of work into fixing imx-drm issues, and I'd like to
make the change to a common device tree binding before this leaves
staging.

Philipp
