[PATCH 0/4] Preemption support for A6xx targets

[Sharat Masetty <smasetty-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

This patch follows Jordan's recent "drm/msm: Add A6XX device support"
patch series and adds preemption support. Preemption allows the GPU to switch
to a higher priority ringbuffer when one is ready, thereby improving user
experience. A6xx hardware supports various preemption levels, each with
different granularities and different switch-out--switch-in times. While this
patch only enables the first preemption level i.e. preemption at the ringbuffer
level, support for more finer grained preemption levels will follow after
more testing.
