v2:
 * Added prototype of possible amdgpu changes and spec updates to align with the
   common spec.

v3:
 * Documented that 'drm-driver' tag shall correspond with
   struct drm_driver.name.

v4:
 * Dropped amdgpu conversion from the series for now until AMD folks can find
   some time to finish that patch.

v5:
 * Added drm-engine-capacity-* tag.
 * Couple small tweaks.

v6:
 * Just a rebase and r-b tags updated.
