Sound Issue with Kernel 4.1.15

PaulDeMetrotion — Thu, 15 Dec 2016 23:11:07 GMT

I am upgrading my i.MX6 kernel to version 4.1.15. I am using the same device tree as the previous version 3.14.28. Audio worked great on the earlier version but I am now getting the following error:

sgtl5000 2-000a: sgtl5000 revision 0x11
imx-sgtl5000 sound: phandle missing or invalid
imx-sgtl5000: probe of sound failed with error -22

My question is has anybody seen this problem? Have the device tree entries for the SGTL5000 changed with the new kernel version?

in the imx-sgtl5000.c

ssi_np = of_parse_phandle(pdev->dev.of_node, "ssi-controller", 0);

codec_np = of_parse_phandle(pdev->dev.of_node, "audio-codec", 0);

if (!ssi_np || !codec_np) {

dev_err(&pdev->dev, "phandle missing or invalid\n");

ret = -EINVAL;

goto fail;

}

So, please check the "ssi-controller" and "audio-codec" are setting correctly in your dtsi file. you can take imx6qdl-sabrelite.dtsi for reference.

Thanks Jimmy!

I had already looked at this but your post made me double check. The imx-sgtl5000.c has indeed changed. Previously the OF parse looked for 'cpu-dai' as a parameter but now it looks for 'ssi-controller'. Made the change in the device tree and everything is good again. Why do they make this kind of unnecessary code change????

Dear Paul,

Please help me how to edit device tree file.

What specifically do you need?

Dear Paul,

I am facing the same issue, which you have said in the query

I am upgrading my i.MX6 kernel to version 4.1.15. I am using the same device tree as the previous version 3.14.28. Audio worked great on the earlier version but I am now getting the following error:

sgtl5000 2-000a: sgtl5000 revision 0x11
imx-sgtl5000 sound: phandle missing or invalid
imx-sgtl5000: probe of sound failed with error -22

My question is has anybody seen this problem? Have the device tree entries for the SGTL5000 changed with the new kernel version?

If you have any solution for the above issue, please share with me.

Here are the relevant sections I have in my device tree. Make sure your mux-int-port and mux-ext-port numbers are correct.

sound {
compatible = "fsl,imx6q-c420-sgtl5000",
"fsl,imx-audio-sgtl5000";
model = "sgtl5000-audio";
cpu-dai = <&ssi2>;
audio-codec = <&sgtl5000>;
audio-routing = "Line Out Jack", "LINE_OUT";
mux-int-port = <2>;
mux-ext-port = <5>;
};

&i2c3 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c3>;
status = "okay";

sgtl5000: sgtl5000@0a {
compatible = "fsl,sgtl5000";
reg = <0x0a>;
VDDA-supply = <&reg_v3p3a>;
VDDD-supply = <&sw4_reg>;
VDDIO-supply = <&reg_v3p3a>;
clocks = <&codec_osc>;
};

eeprom@50 {
compatible = "st-micro,24c256";
reg = <0x50>;
pagesize = <64>;
};
};
