Clock should be enabled as soon as using master modes, even before enabling timer. Or, this may provoke bad behavior on the other end (slave timer). Then, introduce 'clk_enabled' flag, instead of relying on CR1 EN bit, to keep track of clock being enabled (balanced refcount). Propagate this anywhere else in the driver. Also add 'remove' routine to stop timer and disable clock in case it has been left enabled. Enforce the user interface has been unregistered in the remove routine, before disabling the hardware to avoid possible race. So, remove use of devm_ variant to register triggers and unregister them before the hardware gets disabled [1].

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.
