Hi All

I try solve problem with support SGTL5000  under Linux , ARM / ZYNQ 
ARCHITECTURE. Please add this post to "alsa" forum.  If you need any 
others information i can send it .

My post:

  I try use freescale audio chip sgtl5000 on my custom board with Zynq 
chip. I need help with instance driver in device tree and debug first 
execution.

1.*I use I2C* controler to configure sgtl5000 :
/        axi_iic_sgtl: i2c@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@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@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>;
         };/


PS.
Right now i can compile device tree but audio is not detected.
What kind of log do you need to check Linux boot problem ?
