mainlining shenanigans
33a6b48a57
The Fintek F81534A series contains 1 HUB, 1 GPIO device and n UARTs. The UARTs are disabled by default and need to be enabled by the GPIO device (2c42:16F8). When F81534A plug to host, we can only see 1 HUB and 1 GPIO device and we write 0x8fff to GPIO device register F81534A_CTRL_CMD_ENABLE_PORT (116h) to enable all available serial ports.

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.
