Commit84badc5ec5("ARM: dts: omap4: Move l4 child devices to probe them with ti-sysc") moved some omap4 timers to probe with ti-sysc interconnect target module. Turns out this broke pwm-omap-dmtimer where we now try to reparent the clock to itself with the following: omap_dm_timer_of_set_source: failed to set parent With ti-sysc, we can now configure the clock sources in the dts with assigned-clocks and assigned-clock-parents. So we should be able to remove omap_dm_timer_of_set_source with clean-up patches later on. But for now, let's just fix it first by checking if parent and fck are the same and bail out of so.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
