Fix CPU resume latency constraint units sent to device manager through the
TI SCI API. The device manager expects CPU resume latency to be in msecs
which is passed in with the TI SCI API [1]. CPU latency constraints are
set in userspace using the PM QoS framework which uses usecs as the unit.
Since PM QoS uses usecs for units and the device manager expects msecs as
the unit, TI SCI needs to convert from usecs to msecs before passing to
device manager.

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 reStructuredText 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.
