So I have PL111 code almost working here, however today it depends on not-yet-upstream (to my knowledge) generic/common panel/display framework. If I'm not disturbed again I may get something done this week, hopefully removing the dependency. There's also some work going on on a DRM driver for PL111, but I can't promise any dates. As to PL110 I have no idea how different is it from the PL111, but nothing is happening about it anyway. Pawe?
