After a check of the manual it becomes obvious that the calculations in .apply() are totally bogus: FreqPWMOutx was always written as zero, so the period was fixed at 3413333.33 ns. However state->period wasn't checked at all. The lower 10 bits of duty_cycle were just used as DutyPWMOutx. So if a duty cycle of 512 ns (or 1536 ns) was requested, it actually programmed 1710000 ns. Other values were wrong by the same factor. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
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.
