During commit6594988fd6("clk: composite: Use rate_ops.determine_rate when also a mux is available") setting req->best_parent_hw got lost, so best_parent_hw stays NULL during switch to the same parent. This results in the (debug) message: clk_calc_new_rates: lcdif_pixel not gated but wants to reparent and the following rate change is dropped.

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.
