The CPORT mentioned in the CAL documentation has nothing to do with the CSI-2 ports. It's a remnant of CSI-3 support (or an attempt to achieve it), and now only serves as an arbitraty tag value used to associate data samples with contexts. Add a cport field to the cal_ctx structure and use it instead of the CSI-2 port number where a CPORT is required by the hardware. The value of the cport field is currently the same as the csi2_port field, so there's no functional change, but this will help reworking CPORT and CSI-2 port handling separately.

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.
