Add a single imx-media mem2mem video device that uses the IPU IC PP (image converter post processing) task for scaling and colorspace conversion. On i.MX6Q/DL SoCs with two IPUs currently only the first IPU is used. The hardware only supports writing to destination buffers up to 1024x1024 pixels in a single pass, arbitrary sizes can be achieved by rendering multiple tiles per frame. [slongerbeam@gmail.com: use ipu_image_convert_adjust(), fix device_run() error handling, add missing media-device header, unregister and remove the mem2mem device in error paths in imx_media_probe_complete() and in imx_media_remove(), updated for sync subdev registration] Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Steve Longerbeam <slongerbeam@gmail.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> [hverkuil-cisco@xs4all.nl: correct two minor checkpatch issues] [hverkuil-cisco@xs4all.nl: sparse warning: make imx6_media_probe_complete static] Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
