The driver is added in this patch, it's at this uncomfortable stage where I have to make a big upfront design for a new DRM driver and everything is shaky and unreviewed. So to get it out for proper review it needs to be working and to get it working I need review :D DRM development catch 22. But here is the patch adding it all, in some in-flight state: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson.git/commit/?h=ux500-mcde Thanks a lot for these notes, I hope I can figure it out! > 3. drm parent dev depends on panel: this patch adds this dependency. > > If 2nd point is true it becomes circular dependency, but please verify it. I tried to not make the DRM parent dev depend on the panel. AFAICT (1) is true, (2) is true but not (3).
