 *	 The API definition should be freed from fields that are bound to
 *	 some specific data structure.
 *
 * FIXME: Currently, I opted to name the new types as "media_v2", as this
 *	  won't cause any conflict with the Kernelspace namespace, nor with
 *	  the previous kAPI media_*_desc namespace. This can be changed

	259	* NOTE: The declarations below are close to the MC RFC for the Media
	260	* Controller, the next generation. Yet, there are a few adjustments
	261	* to do, as we want to be able to have a functional API before
	262	* the MC properties change. Those will be properly marked below.
	263	* Please also notice that I removed "num_pads", "num_links",
	264	* from the proposal, as a proper userspace application will likely
	265	* use lists for pads/links, just as we intend to do in Kernelspace.
	266	* The API definition should be freed from fields that are bound to
	267	* some specific data structure.
	268	*
	269	* FIXME: Currently, I opted to name the new types as "media_v2", as this
	270	* won't cause any conflict with the Kernelspace namespace, nor with
	271	* the previous kAPI media_*_desc namespace. This can be changed
	272	* later, before the adding this API upstream.
