+ * the special tag.
+ *
+ * This switch intellectual property cannot conform to this part of the standard

+ * @waiting_in_dqbuf: set by the core for the duration of a blocking DQBUF, when

* @is_multiplanar: set if buffer type is multiplanar
* @is_output: set if buffer type is output
* @copy_timestamp: set if vb2-core should set timestamps
