UFS host supplies the reference clock to UFS device and UFS device specification allows host to provide one of the 4 frequencies (19.2 MHz, 26 MHz, 38.4 MHz, 52 MHz) for reference clock. Host should set the device reference clock frequency setting in the device based on what frequency it is supplying to UFS device.

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.
