[PATCH 05/21] drm/imagination: Use more specific compatible strings

Matt Coster
2024-11-05T16:06:37Z

Follow-on from the companion dt-bindings change ("dt-bindings: gpu: img:
More explicit compatible strings"), deprecating "img,img-axe" in favour of
the more specific "img,img-axe-1-16m".

Keep the previous compatible string around for backwards compatibility.
