This allows multiple callers to use the same enum list, but still create different versions of the same property with different list of supported bits. v2: Populate values[] array as non-sparse Make supported_bits 64bit Fix up omapdrm call site (Rob) Cc: Tomi Valkeinen Cc: Rob Clark Cc: Sagar Kamble Cc: dri-devel@lists.freedesktop.org Signed-off-by: Ville Syrjälä --- This should also make my original "drm: Add drm_mode_create_rotation_property()" patch do the right thing.
