[alsa-devel] sgtl5000: probe failed with error -5

[Catalin Crenguta]

I'm working with a phycore vybrid SoM and I'm having some troubles binding
the sgtl5000 audio codec using devicetree.
As you can see, the codec driver could not be probed due to error -5.

The dts looks like this:

sound {
compatible = "fsl,imx-audio-sgtl5000";
model = "phycore-vybrid-sgtl5000";
audio-cpu = <&sai2>;
audio-codec = <&codec>;
audio-routing =
"MIC_IN", "Mic Jack",
"Mic Jack", "Mic Bias",
"Headphone Jack", "HP_OUT";
mux-int-port = <1>;
mux-ext-port = <3>;
};

/* .... */
&i2c2 {
clock-frequency = <400000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c2>;
status = "okay";

/* ... */

codec: sgtl5000 at 0a {
compatible = "fsl,sgtl5000";
reg = <0x0a>;
pinctrl-names = "default";
clocks = <&clks 150>;
micbias-resistor-k-ohms = <2>;
micbias-voltage-m-volts = <2250>;
VDDA-supply = <&reg_3p3v>;
VDDIO-supply = <&reg_3p3v>;
};
};

/* ... */
&iomuxc {
vf610-phycore {
pinctrl_i2c2: i2c2grp {
fsl,pins = <
VF610_PAD_PTA22__I2C2_SCL 0x34d3
VF610_PAD_PTA23__I2C2_SDA 0x34d3
>;
};
};
};

After the system boot, the output of dmesg looks like this:
