The firmware found in some Qualcomm platforms intercepts writes to the S2CR register in order to replace the BYPASS type with FAULT. Further more it treats faults at this level as catastrophic and restarts the device. Add support for providing implementation specific versions of the S2CR write function, to allow the Qualcomm driver to work around this behavior.

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.
