Uwe Kleine-König abf7cf212a pwm: tiehrpwm: Fix corner case in clock divisor calculation
[ Upstream commit 00f83f0e07e44e2f1fb94b223e77ab7b18ee2d7d ]

The function set_prescale_div() is responsible for calculating the clock
divisor settings such that the input clock rate is divided down such that
the required period length is at most 0x10000 clock ticks. If period_cycles
is an integer multiple of 0x10000, the divisor period_cycles / 0x10000 is
good enough. So round up in the calculation of the required divisor and
compare it using >= instead of >.

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.
