The second CSI-2 C-PHY data-lanes have different line orders (BCA) than the two other data-lanes (ABC) for both connected CSI-2 receivers, describe this in the device tree. This has worked in the past as the R-Car CSI-2 driver did not have documentation for the line order configuration, hence magic values were written to the registers for this specific setup. Now the registers involved are documented, the hardware description as well as the driver needs to be updated. Note that the numerical values will be replaced by symbolic values later.

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 reStructuredText 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.
