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 10.
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.
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: 1a6c8fe9a65c26e78ba34bd4aa2df28ede7d00cb,
32 bits
The Media Driver fail some tests but this failures are coming
from code out of
scope of this series (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
v11->v12:
Sakari:
- check v4l2_ctrl_handler_free and init when exposed to
userspace
- check csi_remove missing v4l2_async_notifier_unregister
- media device unregister before ctrl_handler_free
- GPL => GPL v2
- Fix squash of CSI patches, issue on v11
- add Acked-by: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>
10--13
- mipi_s_stream check for ret < 0 and call
pm_runtime_put_noidle
- use __maybe_unused in pm functions
- Extra space before labels
For patches 1, 2 and 4:

Thanks for all your reviews, I did not add this before, because I
messed the patch order in v11.
