This is v4 for a previous patch series being discussed at:

https://lore.kernel.org/dri-devel/20220622015420.1130814-1-adrian.larumbe@collabora.com/T/#t

Mesa MR under review can be found at:

Changes with respect to v3 of the same patch:

 - Remove useless no-op when checking job slot index
 - Actually use JS_SLOT_STRIDE when selecting the right js register.
 - Explain the reason certain GFP flags are picked when allocating memory
 for the coredump file.
 - Move new JS and MMU_AS register offset macros into its own commit.

Adrián Larumbe (2):
  drm/panfrost: Add specific register offset macros for JS and MMU AS
  drm/panfrost: Add support for devcoredump
