[alsa-devel] Post Audio codec sgtl5000 with ARM/Zynq under Linux

[Wojciech Zebrowski]

Hi Nikolay

Thx for your advice , i try use it in feature dts files.
My problem is as below , i can send you boot log or , dmesg log if you 
have any other proposition i can debug it too.

1.*I use I2C* controler to configure sgtl5000 :
         axi_iic_sgtl: i2c at 41610000 {
             #address-cells = <1>;
             #size-cells = <0>;
             compatible = "xlnx,xps-iic-2.00.a";
             interrupt-parent = <&gic>;
             interrupts = <0 31 4>;
             reg = <0x41610000 0x10000>;

             codec: sgtl5000 at 0a {
                 #sound-dai-cells = <0>;
                 compatible = "fsl,sgtl5000";
                 reg = <0x0a>;
/*                VDDA-supply = <&reg_3p3v>; */
/*                VDDIO-supply = <&reg_3p3v>;*/
                 clocks = <&clkc 19>;
       };
*
**  How can i set comment lines ? *

2. sound :
         sound {
            compatible = "fsl,imx51-babbage-sgtl5000",
"fsl,imx-audio-sgtl5000";
            model = "imx51-babbage-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>;
          };/
*I want use I2C configuration driver not SPI . How can i set comment 
line ? **
***
3. I2S driver looks like ok  :
         axi_i2s_adi_0: axi_i2s_adi at 77600000 {
              compatible = "xlnx,axi-i2s-adi-1.0";
              reg = <0x77600000 0x10000>;
              xlnx,bclk-pol = <0x0>;
              xlnx,dma-type = <0x1>;
              xlnx,has-rx = <0x1>;
              xlnx,has-tx = <0x1>;
              xlnx,lrclk-pol = <0x0>;
              xlnx,num-ch = <0x1>;
              xlnx,s-axi-min-size = <0x000001FF>;
              xlnx,slot-width = <0x18>;
          };
