The XSL bit only exists in RS5C372A/B. On other Ricoh RTC chips supported in rs5c372, this bit has different meaning. For example, on R2221x and R2223x, this bit of oscillation adjustment register determines the operation frequency of oscillation adjustment circuit and the oscillation is always 32768HZ. But rs5c372_get_trim gives 32000HZ to osc when DEV is 1.

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.
