[PATCH 0/9] drm/msm/mdp5: Cursor plane stuff

[Archit Taneja]

This series does some mdp5_plane related clean ups (use plane helpers
for clipping etc), adds MDP5 bits needed for cursor plane blocks, and
then add cursor planes.

On older MDP5 versions, we had cursor HW in Layer Mixer blocks, and
that's implemented in mdp5_crtc.c. With newer hardware, the cursor
blocks look exactly like MDP5 pipes (SSPPs).

The "faster than vblank cursor position update stuff" has been
copied from vc4 and the patches posted recently by Maarten for Intel:

https://patchwork.kernel.org/patch/9466417/

I've tried this with some X11 UI and modetest -C, and it seems to
work okay. Are there any tests that mix up atomic commits and legacy
cursor updates a lot to identify issues?
