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",
"fsl,imx-audio-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?
Hi Gary
ssi uses audmux for connection to external devices, please look
at Table 85. AUDMUX Port Allocation i.MX6DQ Datasheet
