Just a heads up, DRM requires an open-source user-space, so if your plan is to move the open-source kernel driver while using the closed-source library (as that page seem to suggest), that might change a few things. > The kernel modules built from this project have successfully > demonstrated to work with the DTS definitions from this patch set on > AM335x BeagleBone Black, DM3730 and OMAP5 Pyra and Droid 4.

If it's not been tested on any Allwinner board yet, I'll leave it aside until it's been properly shown to work. Maxime
