simple-card support it
if it needs convert-rate or convert-channels.
Please check below

	static simple_for_each_link(xxx)
	{
		...
		for_each_child_of_node(node, np) {
			/*
			 * It is DPCM
			 * if it has many CPUs,
			 * or has convert-xxx property
			 */
(1)			if (dpcm_selectable &&
(2)			    (num > 2 ||
(3)			     adata.convert_rate || adata.convert_channels))
				ret = func_dpcm(priv, np, codec, li, is_top);
			...

(1) : using simple-scu-audio-card
(2) : 2 nodes or more
(3) : has convert-xxx property

Thank you for your help !!
Best regards
