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 [0]:
[PATCH v3 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

v1->v2:
Dan Carpenter:
- fix return paths and codes;
- fix clk_frequency validation and return code;
- handle the csi remove (release resources that was missing)
- revert the logic arround the ipu_present flag
Philipp Zabel:
- drop patch that changed the rgb formats and address the pixel/bus format in
mipi_csis code.
MySelf:
- add patch that add ov2680 node to the warp7 dts, so the all data path is
complete.
- add linux-clk mailing list to the clock patches cc:
