[PATCH v2 13/13] drm/msm/adreno: Switch to chip-id for identifying GPU

Rob Clark
2023-07-27T21:24:30Z

Since the revision becomes an opaque identifier with future GPUs, move
away from treating different ranges of bits as having a given meaning.
This means that we need to explicitly list different patch revisions in
the device table.
