Subject: [PATCH] drm/panel: add panel-mipi-dsi-bringup driver
MIME-Version: 1.0
Content-Type: text/plain; charset=3DUTF-8
Content-Transfer-Encoding: 8bit

This driver makes it easy to add new MIPI DSI panel drivers
if one already has panel enabled on the embedded system
without Linux kernel.

I have developed it out of the need because no other driver worked
for me without big amount of changes. Currently it supports fannal C3004.

Documentation/* files will be added in second patch since checkpatch.pl was
complaining.
