Merge tag 'drm-msm-next-2017-08-22' of git://people.freedesktop.org/~robclark/linux into drm-next
Updates for 4.14.. I have some further patches from Jordan to add multiple priority levels and pre-emption, but those will probably be for 4.15 to give me time for the mesa parts. * tag 'drm-msm-next-2017-08-22' of git://people.freedesktop.org/~robclark/linux: drm/msm/mdp5: mark runtime_pm functions as __maybe_unused drm/msm: remove unused variable drm/msm/mdp5: make helper function static drm/msm: make msm_framebuffer_init() static drm/msm: add helper to allocate stolen fb drm/msm: don't track fbdev's gem object separately drm/msm: add modeset module param drm/msm/mdp5: add tracking for clk enable-count drm/msm: remove unused define drm/msm: Add a helper function for in-kernel buffer allocations drm/msm: Attach the GPU MMU when it is created drm/msm: Add A5XX hardware fault detection drm/msm: Remove uneeded platform dev members drm/msm/mdp5: Set up runtime PM for MDSS drm/msm/mdp5: Write to SMP registers even if allocations don't change drm/msm/mdp5: Don't use mode_set helper funcs for encoders and CRTCs drm/msm/dsi: Implement RPM suspend/resume callbacks drm/msm/dsi: Set up runtime PM for DSI drm/msm/hdmi: Set up runtime PM for HDMI drm/msm/mdp5: Use runtime PM get/put API instead of toggling clocks
