In order to use the isp and csi together, both devices need to be parented to the same v4l2 and media devices. We use the isp as top-level device and let the csi code hook to its v4l2 and media devices when async subdev registration takes place. As a result v4l2/media device setup is only called when the ISP is missing and the capture device is registered after the devices are hooked. The bridge subdev and its notifier are registered without any device when the ISP is available. Top-level pointers for the devices are introduced to either redirect to the hooked ones (isp available) or the registered ones (isp missing). Also keep track of whether the capture node was setup or not to avoid cleaning up resources when it wasn't.

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.
