When the system is suspended, we can explicitly disable clock to save power. To achieve this, we need save registers' state since it could be lost after power off. Implement power management which will: - Turn the clock off after probing - Disable clock and save registers' state on system suspend, as well as enable clock and restore registers' state on resume - Rely on the Power Domain framework to shutdown the intmux power domain Without CONFIG_PM, the clock is always on after probe stage.

README
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.
