Merge tag 'drm-msm-next-2018-12-12' of git://people.freedesktop.org/~robclark/linux into drm-next

This time around, seeing some love for some older hw:

 - a2xx gpu support for apq8060 (hp touchpad) and imx5 (headless
   gpu-only mode)
 - a2xx gpummu support (a2xx was pre-iommu)
 - mdp4 display support for apq8060/touchpad

For display/dpu:

 - a big pile of continuing dpu fixes and cleanups

On the gpu side of things:

 - per-submit statistics and traceevents for better profiling
 - a6xx crashdump support
 - decouple get_iova() and page pinning.. so we can unpin from
   physical memory inactive bo's while using softpin to lower
   cpu overhead
 - new interface to set debug names on GEM BOs and debugfs
   output improvements
 - additional submit flag to indicate buffers that are used
   to dump (so $debugfs/rd cmdstream dumping is useful with
   softpin + state-objects)
