Changes in v1:
-Modify commit text to indicate DSI version and SOC detail(Jeffrey Hugo).
-Splitting visionox panel driver code out into a
different patch(set), since panel drivers are merged into
drm-next via a different tree(Rob Clark).

The change log shouldn't be part of the commit message, please place it
after the '---' separator.
I think at least a one line commit message besides the subject is
mandatory, so if you move the change log down you'll have to add
some short summary.

jfyi, the changelog and version #'s showing up in final commit msg is
one thing that drm does differently from other parts of the kernel.
So it is ok to keep the changelog before "---".
But agreed about the need for a commit message (in addition to just
the changelog)
