Add support for the two- and four-port variants of XR21V1410. Use the interface number of each control interface (e.g. 0, 2, 4, 6) to derive the zero-based channel index: XR21V1410 0 XR21V1412 0, 1 XR21V1414 0, 1, 2, 3 Note that the UART registers reside in separate blocks per channel, while the UART Manager functionality is implemented using per-channel registers.

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.
