[PATCH v4 00/14] 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.

main changes in this v4:
* fixing the reset serialization
* fixing a deadlock in the reset path
* moving the exception enum to a private header

Regards,

Boris
