Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
A bit smaller pull-req this time around. Some continued DT binding
cleanup to get the corresponding dts bits merged upstream (through
other trees). And explicit fence-fd support for submit ioctl.
* 'msm-next' of git://people.freedesktop.org/~robclark/linux:
drm/msm: bump kernel api version for explicit fencing
drm/msm: submit support for out-fences
drm/msm: move fence allocation out of msm_gpu_submit()
drm/msm: submit support for in-fences
drm/msm: extend the submit ioctl to pass in flags
drm/msm/mdp5: Set rotation property initial value to DRM_ROTATE_0 insted of 0
drm/msm/hdmi: don't print error when adding i2c adapter fails
drm/msm/mdp4: mark symbols static where possible
drm/msm: Remove call to reservation_object_test_signaled_rcu before wait
drm/msm/hdmi: Clean up HDMI gpio DT bindings
drm/msm/mdp4: Fix issue with LCDC/LVDS port parsing
