Subject: [PATCH 0/7] drm/mcde: DSI video mode fixes

This is a collection of fixes to make DSI video mode work better
using the MCDE driver. With these changes, MCDE appears to work
properly for the video mode panel I have been testing with.

Note: The patch that fixes the DSI link register setup for
video mode [1] is still necessary; but we still need to finish it
and actually make it initialize a panel correctly.

This series contains only patches for the other parts in MCDE.
I have tested it by disabling most of the register setup in the
DSI driver, which makes it re-use the properly working DSI register
set by the bootloader.
