mainlining shenanigans
a9082575f8
When I re-posted Sean's original commit to add the override mode for
the kevin panel, for some reason I didn't notice that the pixel clock
wasn't quite right. Looking at /sys/kernel/debug/clk/clk_summary on
downstream kernels it can be seen that the VOP clock is supposed to be
266,666,667 Hz achieved by dividing the 800 MHz PLL by 3.
Looking at history, it seems that even Sean's first patch [1] had this
funny clock rate. I'm not sure where it came from since the commit
message specifically mentioned 26666 kHz and the Chrome OS tree [2]
can be seen to request 266667 kHz.
In any case, let's fix it up. This together with my patch [3] to do
the proper rounding when setting the clock rate makes the VOP clock
more proper as seen in /sys/kernel/debug/clk/clk_summary.

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.
