-Subject: [PATCH] drm/vc4: Add support for rendering with ETC1 textures.
-
-The validation for it ends up being quite simple, but I hadn't got
-around to it before merging the driver. For backwards compatibility,
-we also need to add a flag so that the userspace GL driver can easily
-tell if the kernel will allow ETC1 textures (on an old kernel, it will
-continue to convert to RGBA8)
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-(cherry picked from commit 7154d76fedf549607afbc0d13db9aaf02da5cebf)
