This device is powered by an FT232H, which is very similar to the FT2232H this driver was written for. The key difference is it has only one MPSSE instead of two. As a result, it presents only one USB interface to the system, which conveniently "just works" out of the box with this driver. The brik exposes only two GPIO lines which are hardware limited to only be useful in one direction. As a result, I've restricted things on the driver side to refuse to configure any other lines. This device, unlike the sealevel device I wrote this driver for originally, is hotpluggable, which makes for all sorts of weird edgecases. I've tried my best to stress-test the parts that could go wrong, but given the new usecase, more heads taking a critical look at the teardown and synchronization bits on the driver as a whole would be appreciated.

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.
