2d82d188b2 drm/msm: Switch to universal plane API's
Use drm_universal_plane_init() and drm_crtc_init_with_planes() rather
than the legacy drm_plane_init() / drm_crtc_init().  This will ensure
that the proper primary plane is registered with the DRM (and eventually
exposed to userspace in future patches).

06c0dd96bf drm/msm: add mdp5/apq8x74
Add support for the new MDP5 display controller block.  The mapping
between parts of the display controller and KMS is:

  plane   -> PIPE{RGBn,VIGn}             \
  crtc    -> LM (layer mixer)            |-> MDP "device"
  encoder -> INTF                        /
  connector -> HDMI/DSI/eDP/etc          --> other device(s)

Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc.  (Ie. the
register interface is same, just different bases.)

Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
routed through MDP.

And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
which blocks need to be allocated to the active pipes based on fetch
stride.
