[PATCH v3 00/15] drm/panfrost: Misc improvements

[Boris Brezillon]

Hello,

This is a merge of [1] and [2] since the second series depends on
patches in the preparatory series.

The main change in this v3 is the addition of patch 1 and 9 simplifying
the reset synchronisation as suggested by Daniel.

Also addressed Steve's comments, and IGT tests are now passing reliably
(which doesn't guarantee much, but that's still an improvement since
pan-reset was unreliable with v2).

Regards,

Boris
