Hi All,
The following is the state-of-the-art i.MX IPU (Image Processing Unit)
DRM support.
This code is around for quite some time now and has been posted several
times with different APIs, first with plain old framebuffer support, now
DRM, first platform device binding, now devicetree. Unfortunately there's
quite much code needed to get something useful out of the IPU, so these
patches haven't received a lot of attention from people not involved in
i.MX. I think we have now come to a point where this code needs more public
exposure and where it's easier to talk in incremental changes instead of
blobs. Therefore I request this to go to staging for some cycles. This
would allow us to have something in mainline as a base for further discussion
while still being able to change bigger amounts of the driver without breaking
officially supported features. What do you think about this?
The IPU driver generally works on i.MX51, i.MX53 and i.MX6. The latter has
two IPUs, the driver is able to handle them both.
This series only contains the IPU driver. There are some additional glue
code patches necessary. Also necessary are two drm CMA/GEM helper patches
currently waiting for review on dri-devel. For testing the driver please
use this branch:
git://git.pengutronix.de/git/imx/linux-2.6.git work/gpu/imx-drm-ipu-complete
The branch contains board support for the i.MX51 babbage (both digital and
analog DVI outputs are supported) and i.MX6q armadillo2 (HDMI). Compile
with imx_v6_v7_defconfig.
For discussion of the devicetree binding please refer to the seperate mail
I sent.
As usual, all comments/suggestions welcome
Sascha
