HHI_VID_DIVIDER_CNTL[11] must be enabled for the video clock tree to work. This bit is described as "LVDS_CLK_EN". It is not 100% clear where this bit has to be placed in the hierarchy. But since the "LVDS_OUT" of the HDMI PLL uses it's own set of registers it's more likely that this "LVDS_CLK_EN" bit actually enables the input of the "hdmi_pll_lvds_out" clock to the "vid_pll_in_sel" tree. Add a gate definition for this bit (which will not be exported) so that the kernel can manage all required bits to enable and disable the video clocks.

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.
