Alexander Kochetkov f086ebcfec clocksource/arm_global_timer: reconfigure clockevents after cpufreq change
After a cpufreq transition, update the clockevent's frequency
by fetching the new clock rate from the clock framework and
reprogram the next clock event.

The clock supplying the arm-global-timer on the rk3188 is coming
from the the cpu clock itself and thus changes its rate everytime
cpufreq adjusts the cpu frequency.

Found by code review, real impact not known. Assume what actual
HZ value will be different from expected on platforms using
arm-global-timer as clockevent.

The patch is port of commit 4fd7f9b128 ("ARM: 7212/1: smp_twd:
reconfigure clockevents after cpufreq change") and
commit 2b25d9f64b ("ARM: 7535/1: Reprogram smp_twd based on
new common clk framework notifiers").

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
