Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: "A few imx fixes I missed from a couple of weeks ago, they still aren't that big and fix some regression and a fail to boot problem. Other than that, a couple of regression fixes for radeon/amdgpu, one regression fix for vmwgfx and one regression fix for tda998x" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: Revert "drm/radeon/pm: adjust display configuration after powerstate" drm/amdgpu/dp: add back special handling for NUTMEG drm/radeon/dp: add back special handling for NUTMEG drm/i2c: tda998x: Choose between atomic or non atomic dpms helper drm/vmwgfx: Add back ->detect() and ->fill_modes() drm/radeon: Fix error handling in radeon_flip_work_func. drm/amdgpu: Fix error handling in amdgpu_flip_work_func. drm/imx: Add missing DRM_FORMAT_RGB565 to ipu_plane_formats drm/imx: notify DRM core about CRTC vblank state gpu: ipu-v3: Reset IPU before activating IRQ gpu: ipu-v3: Do not bail out on missing optional port nodes
