Hello,
Bunch of improvements to make the panfrost driver more robust and allow
queuing jobs at the HW level.
Changes in v6:
* Collected acks/reviews
* Got rid of the cancel_delayed_work() calls in the reset path
Changes in this v5:
* Document what's excepted in the ->timedout_job() hook
* Add a patch increasing the AS_ACTIVE polling timeout
* Fix a few minor things here and there (see each commit for a detailed
changelog) and collect R-b/A-b tags
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
