The R-Car Gen3 HardWare Manual Errata for Rev. 1.00 (Jul 2, 2018) states
that the USB30_OVC pin supports pull-up only. It has a bit assigned in
the pull-enable register (PUEN5), but not in the pull-up/down control
register (PUD5).
Add a check for this, to prevent configuring a prohibited setting.

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.
