[Freedreno] [PATCH 0/6] Preemption support for A6xx targets

[Sharat Masetty]

This is a revised preemption support patchset follows Jordan's recent
"drm/msm: Add A6XX device support" patch series. 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.

This series starts off by adding basic preemption support for A6xx targets,
leading up to the tip of the stack which enables L1 level preemption.
This is a more fine grained version and faster than the default level.
