FYI, This is working !
I can capture my sound from line in with this :
    sound {
        compatible = "fsl,imx6q-vbx3-sgtl5000",
                 "fsl,imx-audio-sgtl5000";
        model = "imx6q-vbx3-sgtl5000";
        ssi-controller = <&ssi1>;
        audio-codec = <&codec>;
        audio-routing =
            "A1N1L", "Line In Jack",
            "A1N1R", "Line In Jack";
        mux-int-port = <1>;
        mux-ext-port = <5>;
    };

Now, I will add mic support, and I still need to modprobe manually, I
need to know why...

Thanks,
JM
