Userspace may want to manually control when the data should go into WriteBooster buffer. The control happens via "wb_on" node, but presently, there is no simple way to check if WriteBooster is supported and enabled. Expose the Write Booster and Clock Scaling capabilities to be able to determine if the Write Booster is available and if its manual control is blocked by Clock Scaling mechanism.

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.
