This series cleans up duplicated code for replacing firmware FB driver with proper DRI driver and adds handover support to Tegra driver. The last patch is here because it uses new semantics of remove_conflicting_framebuffers() from this series. This can be considered independently, though. --- Micha?

This series cleans up duplicated code for replacing firmware FB driver with proper DRI driver and adds handover support to Tegra driver. This is a sligtly updated version of a series sent on 24 Nov 2017. --- v2: - rebased on current drm-next - dropped staging/sm750fb changes - added kernel docs for DRM helpers v3: - move kerneldoc to fbdev, where functions are implemented - split kerneldoc

This series is intended to add support for shutting down the GPU on kernel shutdown/reboot using the ->shutdown() hook, similar to what amdgpu does. This is mainly intended to workaround a bios issue on the P50 that was preventing nouveau from initializing the dedicated GM107 GPU on that system properly. You can find more details on this issue in the patch labeled "Shut down GPU on kernel
