For controller which is managed by PD (power-domain),
when PD off, the controller is reset to the default
status, and the FRAC-DIV is a fixed value(1/20).
Once the mclk is enabled, there are some high freq cycle
leak, to fix this issue, we use the pinctrl-idle to
block these cycles until the config has been come back
to the normal state.

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.
