[PATCH v5 0/4] drm/vc4: Binner BO management improvements

[Paul Kocialkowski <paul.kocialkowski@bootlin.com>]

Changes since v4:
* Used a kref on the binner bo instead of firstopen/lastclose;
* Added a mutex to prevent race conditions;
* Took care of enabling the OOM interrupt when we have a binner BO allocated.

Changes since v3:
* Split changes into more commits when possible;
* Reworked binner bo alloc condition as discussed.

Changes since v2:
* Removed deprecated sentence about fristopen;
* Added collected Reviewed-By tags.

Changes since v1:
* Squashed the two final patches into one.

Paul Kocialkowski (4):
  drm/vc4: Reformat and export binner bo allocation helper
  drm/vc4: Check for V3D before binner bo alloc
  drm/vc4: Check for the binner bo before handling OOM interrupt
  drm/vc4: Allocate binner bo when starting to use the V3D
