[yocto][linux-imx to linux-fslc] CLK01 activation

799 Views

Hi everyone,

 

I'm using a board equiped with IMX6 dual Lite, with codec sgtl5000, clk01 (on GPIO_0) is used as master clock for the sgtl5000.

The build system is yocto on branch krogoth

With linux-imx, everything was fine.

then I switched to Linux-fslc, now the sgtl5000 is not detected anymore, I could see that the clock is not generated anymore...

I checked the i2c control signals, everything is fine on the bus, but as the master clock is not available, the chip doesn't answer...

So now the sgtl 5000 is not detected anymore on the I2C bus

 

My question is :

How can I get this clock generated/activated? maybe something is missing in my devicetree but as I didn't modified it I don't know what it could be.

 

Thanks for any help

Aurele

 

 

I joined the content of /sys/kernel/debug/clk/clk_summary file. I saw that CKO clocks are not active at all

 

below some pieces of my devicetree :

 

&i2c2 {

  status = "okay";

  clock-frequency = <100000>;

  pinctrl-names = "default";

  pinctrl-0 = <&pinctrl_i2c2_moniteur>;

  codec: sgtl5000@0a {

  compatible = "fsl,sgtl5000";

  reg = <0x0a>;

  clocks = <&clks 201>;

  VDDA-supply = <&reg_3p3v>;

  VDDIO-supply = <&reg_3p3v>;

  };

};

 

&ssi1 {

  fsl,mode = "i2s-slave";

  status = "okay";

};

 

sound {

  compatible = "fsl,imx6dl-moniteur-sgtl5000", "fsl,imx-audio-sgtl5000";

  model = "imx6dl-moniteur-sgtl5000";

  ssi-controller = <&ssi1>;

  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>;

  };

 

in iomuxc section :
