Oops, my driver is using multi ports already.
it is handling like below

	+-- Board  -------------+
	|+--------+     +------+|
	||SoC  (A)|<--->|Codec1|| Sound Card0
	||        |     +------+|
	||     (B)|<-+          |
	|+--------+  |          |
	+------------|----------+
	+-- Expansion board ----+
	|            |  +------+|
	|            +->|Codec2|| Sound Card1
	|               +------+|
	+-----------------------+

Here (A) is handled by ports0, and (B) is handled by ports1,
and each ports has many port nodes.


Thank you for your help !!
