mainlining shenanigans
9af1fba33b
The switch to the atomic API goes hand in hand with a few fixes to previously experienced issues: - The duty cycle is no longer lost after disable/enable (previously the OFF registers were cleared in disable and the user was required to call config to restore the duty cycle settings) - If one sets a period resulting in the same prescale register value, the sleep and write to the register is now skipped - Previously, only the full ON bit was toggled in GPIO mode (and full OFF cleared if set to high), which could result in both full OFF and full ON not being set and on=0, off=0, which is not allowed according to the datasheet - The OFF registers were reset to 0 in probe, which could lead to the forbidden on=0, off=0. Fixed by resetting to POR default (full OFF) Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com> Acked-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.
