imx6q sabresd board: SSI config problem

According to the schematics, the sound card WM8962 is connected to I2S-3 as the picture indicates.



But in the device tree file "imx6qdl-sabresd.dtsi", the related device node is :

sound {

      compatible = "fsl,imx6q-sabresd-wm8962",


     model = "wm8962-audio";

     cpu-dai = <&ssi2>;

     audio-codec = <&codec>;

     ... ...



In the "imx6qdl.dtsi", 3 device node: "ssi1", "ssi2", "ssi3" are defined.


Why the device node above doesn't use <&ssi3> ? Is there a "logic device name" and "physical device name" mapping table?
