Rui Miguel Silva Feb. 4, 2019, noon
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
