During graceful shutdown scenario, host will issue MHI RESET to the endpoint device before initiating shutdown. In that case, it makes sense to completely power down the MHI stack as sooner or later the access to MMIO registers will be prohibited. Also, the stack needs to be powered up in the case of SYS_ERR to recover the 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.
