There are a few clocks whose parents are set in mipi_dsi
and lcdif nodes, but these clocks are used by the media_blk_ctrl
power domain. This may cause an issue when re-parenting, because
the media_blk_ctrl may start the clocks before the reparent is
done resulting in a disp_pixel clock having the wrong parent and
rate.
Fix this by moving the assigned-clock-parents and rates to the
media_blk_ctrl node to configure these clocks before they are enabled.
After this patch, both disp1_pix_root and dixp2_pix_root clock
become children of the video_pll1.

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.
