The function omap_dm_timer_of_set_source() was originally added in commit31a7448f4f("ARM: OMAP: dmtimer: Add clock source from DT"), and is designed to set a clock source from DT using the clocks property of a timer node. This design choice is okay for clk provider nodes but otherwise is a bad design as typically the clocks property is used to specify the functional clocks for a device, and not its parents. The timer nodes now all define a timer functional clock after the conversion to ti-sysc and the new clkctrl layout, and this results in an attempt to set the same functional clock as its parent when a consumer driver attempts to acquire any of these timers in the omap_dm_timer_prepare() function. This was masked and worked around in commit983a5a43ec("clocksource: timer-ti-dm: Fix pwm dmtimer usage of fck reparenting"). Fix all of this by simply dropping the entire function. Any DT configuration of clock sources should be achieved using assigned-clocks and assigned-clock-parents properties provided by the Common Clock Framework.

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.
