+ * DOC: standard plane properties

+ * DRM planes have a few standardized properties:
+ *
+ * IN_FORMATS:
+ * Blob property which contains the set of buffer format and modifier
+ * pairs supported by this plane. The blob is a drm_format_modifier_blob
+ * struct. Without this property the plane doesn't support buffers with
+ * modifiers. Userspace cannot change this property.
