This is my WIP development branch for converting the panel-dsi-cm
driver into a drm_panel. The driver still is in omapdrm/displays in
the branch, but it is free of any omapdrm specific things and can
trivially be moved to drm/panels.
The branch is working on Droid 4, but panel unblanking after a blank
results in a kernel crash. Also system shutdown results in a kernel
crash. I plan to send out the series once I fixed these issues.
