In MT8195 SOF design, both DSP and audio driver would access audio registers. Before DSP accesses audio registers, audio power and clock should be enabled. DSP will hang up if DSP access audio register but audio power and clock are disabled. Therefore, we add audio pm runtime active checking before accessing audio registers in SOF BE's callback hw_params function to avoid this situation.

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.
