Currently the "Force Power" logic uses 10 retries, each with a delay of 250 ms. Thunderbolt controllers in Ice Lake and Tiger Lake platforms are found to complete this in the order of 3 ms or so. Since this delay is in resume path, surplus delay is effectively affecting runtime PM resume flows. Decrease the granularity of the delay to 3 ms and increase the number of retries so we wait maximum of ~1 s which is the recommended timeout. This should make runtime resume a bit faster.

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.
