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

17 Jun 2015

      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@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  :

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>;//

//            compatible = "xlnx,xps-iic-2.00.a";//
//            interrupt-parent = <&gic>;//
//            interrupts = <0 31 4>;//
//            reg = <0x41610000 0x10000>;//
////
//            codec: sgtl5000@0a {//
//                #sound-dai-cells = <0>;//

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 ?
Comments in DTS files are done the old-school C way, /* */.
Changed

Regarding the SGTL5K configuration, please take a look here for
reference:
https://github.com/torvalds/linux/blob/0f57d86787d8b1076ea8f9cbdddda2a46d534...
I thing it is the same as my .
...
If the audio codec device is detected during boot, you should see
something like this in you boot logs:
...
sgtl5000 0-000a: sgtl5000 revision 0x11
sgtl5000 0-000a: Using internal LDO instead of VDDD
imx-sgtl5000 sound: sgtl5000 <-> 2028000.ssi mapping ok
...
Nothing

ALSA device list:
#0: imx6-riotboard-sgtl5000
