Hi,
This series introduces the Media driver to work with the i.MX7
SoC. it uses the
already existing imx media core drivers but since the i.MX7,
contrary to
i.MX5/6, do not have an IPU and because of that some changes in
the imx media
core are made along this series to make it support that case.
This patches adds CSI and MIPI-CSI2 drivers for i.MX7, along
with several
configurations changes for this to work as a capture subsystem.
Some bugs are
also fixed along the line. And necessary documentation.
For a more detailed view of the capture paths, pads links in
the i.MX7 please
take a look at the documentation in PATCH 14.
The system used to test and develop this was the Warp7 board
with an OV2680
sensor, which output format is 10-bit bayer. So, only MIPI
interface was
tested, a scenario with an parallel input would nice to have.
*Important note*, this code depends on Steve Longerbeam series

[PATCH v4 00/13] media: imx: Switch to subdev notifiers
which the merging status is not clear to me, but the changes in
there make
senses to this series
Bellow goes an example of the output of the pads and links and
the output of
v4l2-compliance testing.
The v4l-utils version used is:
v4l2-compliance SHA :
47d43b130dc6e9e0edc900759fb37649208371e4 from Apr 4th.
The Media Driver fail some tests but this failures are coming
from code out of
scope of this series (video-mux, imx-capture), and some from
the sensor OV2680
but that I think not related with the sensor driver but with
the testing and
core.
The csi and mipi-csi entities pass all compliance tests.
Cheers,
Rui

This patch series was delayed quite a bit since the patch series
above
it depends on is still not merged.
But the v6 version of that series will be merged once the 4.20
cycle opens:

Good news.
Sakari has a branch with that series on top of the latest
media_tree master:
https://git.linuxtv.org/sailus/media_tree.git/log/?h=v4l2-fwnode
Can you rebase this imx7 series on top of that? And test it
again with the
*latest* v4l2-compliance? (I've added new checks recently, so
you need to
update this utility)
Please post the output of the v4l2-compliance test (after fixing
any issues
it raises of course), either as a reply to this post or in the
cover letter
of a v7 version of this series if you had to make changes.
Sure, I will rebase on top of Sakari tree and will update the
compliance
tests and run them again.
This should expedite merging this series for 4.20.
Thanks!
Hans
Ok, thanks for this. I will try to do it soon.
