[PATCH 0/6] drm/v3d: Fix GPU reset issues on the Raspberry Pi 5

["Maíra Canal" <mcanal@igalia.com>]

This series addresses GPU reset issues reported in [1], where running a
long compute job would trigger repeated GPU resets, leading to a UI
freeze.

Patches #1 and #2 prevent the same faulty job from being resubmitted in a
loop, mitigating the first cause of the issue.

However, the issue isn't entirely solved. Even with only a single GPU
reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang.
Patches #3 to #5 address this by properly configuring the V3D_SMS
registers, which are required for power management and resets in V3D 7.1.

Patch #6 updates the DT maintainership, replacing Emma with the current
v3d driver maintainer.

      drm/v3d: Don't run jobs that have errors flagged in its fence
      drm/v3d: Set job pointer to NULL when the job's fence has an error
      drm/v3d: Associate a V3D tech revision to all supported devices
      dt-bindings: gpu: v3d: Add SMS to the registers' list
      drm/v3d: Use V3D_SMS registers for power on/off and reset on V3D 7.x
      dt-bindings: gpu: Add V3D driver maintainer as DT maintainer
