Export find_pipeline_pad(), renaming to imx_media_pipeline_pad(), and extend its functionality to allow searching for video devices in the enabled pipeline in addition to sub-devices. As part of this: - Rename imx_media_find_mipi_csi2_channel() to imx_media_pipeline_csi2_channel(). - Remove imx_media_find_upstream_pad(), it is redundant now. - Rename imx_media_find_upstream_subdev() to imx_media_pipeline_subdev() with an additional boolean argument for searching upstream or downstream. - Add imx_media_pipeline_video_device() which is analogous to imx_media_pipeline_subdev() but searches for video devices. - Remove imxmd pointer arg from all of the functions above, it was never used in those functions. With that change the i.MX5/6 CSI, VDIC, and IC sub-devices no longer require the media_device.

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.
