Subject: [PATCH v1 0/9] drm/amd/pm runtime pm changes

This series rework how runtime power management is handled in drm/amd/pm.

The main ideas are:
* simplify code and reduce copy-pate of runtimepm calls
* avoid waking up suspended GPU when reading debugfs files.

It is similar to Mario's earlier series:
   https://lists.freedesktop.org/archives/amd-gfx/2024-August/113213.html
It's not a direct successor of it, hence v1.
Instead, this is part of a larger series that applies the same ideas to the whole amdgpu module.


Pierre-Eric Pelloux-Prayer (9):
  drm/amd/pm: remove dump_pptable functions
  drm/amd/pm: fix rpm refcount handling on error
  drm/amd/pm: use pm_runtime_resume_and_get
  drm/amd/pm: don't update runpm last_usage on debugfs getter
  drm/amd/pm: use pm_runtime_get_if_active for debugfs getters
  drm/amd/pm: stop extra checks for runtime pm state
  drm/amd/pm: add sysfs attribute access wrappers
  drm/amd/pm: move private definitions to the .c file
  drm/amd/pm: use pm_runtime_get_if_active in amdgpu_debugfs_sensor_read
