For rk3576 and rk3588, vop dclk can be from pll or hdmi phy[except hdmi
2.1(dclk bigger than 597M), the HDMI work at FRL mode], when dclk is
from pll, dclk_parent is equal to dclk, we need clk_round_rate() for
dclk_parent to check whether can support this mode.

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.
