This adds the initial driver for panfrost which supports Arm Mali Midgard and Bifrost family of GPUs. Currently, only the T860 and T760 Midgard GPUs have been tested. v2: - Add GPU reset on job hangs (Tomeu) - Add RuntimePM and devfreq support (Tomeu) - Fix T760 support (Tomeu) - Add a TODO file (Rob, Tomeu) - Support multiple in fences (Tomeu) - Drop support for shared fences (Tomeu) - Fill in MMU de-init (Rob) - Move register definitions back to single header (Rob) - Clean-up hardcoded job submit todos (Rob) - Implement feature setup based on features/issues (Rob) - Add remaining Midgard DT compatible strings (Rob) v3: - Add support for reset lines (Neil) - Add a MAINTAINERS entry (Rob) - Call dma_set_mask_and_coherent (Rob) - Do MMU invalidate on map and unmap. Restructure to do a single operation per map/unmap call. (Rob) - Add a missing explicit padding to struct drm_panfrost_create_bo (Rob) - Fix 0-day error: "panfrost_devfreq.c:151:9-16: ERROR: PTR_ERR applied after initialization to constant on line 150" - Drop HW_FEATURE_AARCH64_MMU conditional (Rob) - s/DRM_PANFROST_PARAM_GPU_ID/DRM_PANFROST_PARAM_GPU_PROD_ID/ (Rob) - Check drm_gem_shmem_prime_import_sg_table() error code (Rob) - Re-order power on sequence (Rob) - Move panfrost_acquire_object_fences() before scheduling job (Rob) - Add NULL checks on array pointers in job clean-up (Rob) - Rework devfreq (Tomeu) - Fix devfreq init with no regulator (Rob) - Various WS and comments clean-up (Rob) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Steven Price <steven.price@arm.com> Signed-off-by: Marty E.
