Michal Wilczynski a9b95b7bea clk: thead: Correct parent for DPU pixel clocks 
[ Upstream commit c51a37ffea ]

The dpu0_pixelclk and dpu1_pixelclk gates were incorrectly parented to
the video_pll_clk.

According to the TH1520 TRM, the "dpu0_pixelclk" should be sourced from
"DPU0 PLL DIV CLK". In this driver, "DPU0 PLL DIV CLK" corresponds to
the `dpu0_clk` clock, which is a divider whose parent is the
`dpu0_pll_clk`.

This patch corrects the clock hierarchy by reparenting `dpu0_pixelclk`
to `dpu0_clk`. By symmetry, `dpu1_pixelclk` is also reparented to its
correct source, `dpu1_clk`.

Fixes: 50d4b157fa ("clk: thead: Add clock support for VO subsystem in T-HEAD TH1520 SoC")

README 

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 reStructuredText 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.
