Sebastian, if > you've looked into it, could you provide some insight ? I have a rebased & tested version of the patches getting the Droid 4 panel working in this branch (together with 2 patches adding backlight support for testing purposes). I will send it as a patch series in a few minutes. https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-n900.git/log/?h=omapdrm-5.2-with-dsi I also had a look at converting to DRM bridge/panel model and started working on it in the following branch. It's completley untested and probably not working at all. Also the most recent patches are not yet properly splitted / formated. But they show my idea of how this can be achieved: 1. Add DSI transfer() function 2. Convert custom functions to use transfer() instead 3. Convert to use mipi_dsi_host 4. Get rid of custom DSI related omapdss functions 5. at this point panel conversion can hopefully happen the same way as for the other modules https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-n900.git/log/?h=omapdrm-5.2-with-dsi-untested-work-branch P.S.: I will continue to work on this, but probably not in the next 4 weeks. I'm currently very busy with non-kernel tasks and still have to review > 200 power-supply patches. -- Sebastian
