37 Possible `drm-engine-` key names are: `panthor`.
38 `drm-curfreq-` values convey the current operating frequency for that engine.

50 Possible `panthor-*-memory` keys are: `active` and `resident`.
51 These values convey the sizes of the internal driver-owned shmem BO's that
52 aren't exposed to user-space through a DRM handle, like queue ring buffers,
54 at creation time, only `panthor-resident-memory` is necessary to tell us their
55 size. `panthor-active-memory` shows the size of kernel BO's associated with
