[PATCH] drm/msm/rd: Add chip-id

From: Rob Clark
Date: Fri Jan 14 2022 - 13:57:39 EST


From: Rob Clark <robdclark@xxxxxxxxxxxx>

For newer devices which deprecate gpu-id and do matching based on
chip-id, we need this information in cmdstream dumps so that the
decoding tools know how to decode them.
