Dear all

 

I want to carete the 24MHz from ping GPIO_0 based on imx6dl.

 

I modify the pinmux setting

      MX6QDL_PAD_GPIO_0__CCM_CLKO1    0x1b0b0

 

And I use the mclk 24 MHze for wm8960

    codec: wm8960@1a {
        compatible = "wlf,wm8960";
        reg = <0x1a>;
        clocks = <&clks IMX6QDL_CLK_CKO>;
        clock-names = "mclk";
        mclk = <24000000>;
        mclk_source = <0>;

 

        wlf,shared-lrclk;
       };

 

But it always cannot get the 24MHz, and show the error message "ASoC: HiFi startup failed: -16".
