[why] As per programming guide, we need to enable the virtual pixel clock via DTBCLK DTO and ungate the clock before we begin programming OPP/OPTC control registers. Otherwise, the double-buffered registers will be left pending until the clocks are enabled. [how] Move the DTBCLK DTO programming up to where we do the legacy DP DTO programming.

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.
