In some cases when firmware is busy or updating, some mailbox commands still timeout on some newer CPUs. To fix this issue, change how we process timeout. With this change, replaced timeout from using simple count with real timeout in micro-seconds using ktime. When the command response takes more than average processing time, yield to other tasks. The worst case timeout is extended upto 1 milli-second.

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.
