Currently the Ice Lake and Tiger Lake NHI (host controller) LC (link controller) mailbox command processing checks for the completion of command every 100 msecs. These controllers are found to complete this in the order of 1 ms or so. Since this delay is in suspend path, surplus delay is effectively affecting runtime PM suspend flows. Optimize this so that we do the wait for 1 ms after reading the mailbox register. This should make Ice Lake and Tiger Lake runtime suspend take less time to complete.

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.
