The UART ports created by this driver were not usable out of the box, so let the configuration be handled by the 8250 UART subsystem. This makes the implementation simpler and the UART port more usable. The 8250 UART subsystem will take care of requesting the memory resources, but the driver needs to first read the register where the num ports is set, so a request of the resource is needed before registering the UART port.

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.
