This updates the existing omapdrm DSI code, so that it uses common drm_mipi_dsi API and drm_panel instead of custom API. I did not implement support for drm_bridge, since I do not own any hardware needing this and it does not seem to be a supported scenario with the old DSS code.
The patchset has been tested with Droid 4 using Linux console, X.org and Weston. While I found some issues, I could not find any regressions compared to the current state (*). Combined with Laurent's effort this will remove all custom panel/connector drivers from omapdrm and allow more cleanups in the DSS code.
I pushed this patchset into the following branch:
https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-n900.git/log/?h=om...
(*) When display is used as console for dmesg one can see an ugly deadlock on shutdown. I have not yet found the root cause for this problem, but that already exists with current mainline implementation.
