The parent of disp_cc_mdss_byte0_intf_clk clock should not propagate up
the rates, because this messes up entire clock hierarchy when setting
clock rates in MSM DSI driver.
The dsi_link_clk_set_rate_6g() first sets entire clock hierarchy rates
via dev_pm_opp_set_rate() on byte clock and then sets individual clock
rates, like pixel and byte_intf clocks, to proper frequencies. Having
CLK_SET_RATE_PARENT caused that entire tree was re-calced and the byte
clock received halved frequency. Drop CLK_SET_RATE_PARENT to fix this
and align with SM8550 and SM8650.

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.
