I think I have gotten around this problem using the code in the samsung/smdk_wm8994.c probe function : implant_dai.cpu_dai_name = NULL; implant_dai.cpu_of_node = of_parse_phandle(np, "samsung,i2s-controller", 0); implant_dai.platform_name = NULL; implant_dai.platform_of_node = implant_dai.cpu_of_node;

Now having problems with the codec registration : .codec_name = "implant-codec",

ASoC: CODEC implant-codec not registered

I am looking for the magic here ...

Any ideas ?

I solved this problem using the following code : implant_dai.codec_name = NULL; implant_dai.codec_of_node = of_parse_phandle(np, "samsung,audio-codec", 0);

Thanks for the idea ... I have set this : i2s0: i2s@03830000 { status = "okay"; };

and I get the same problem.

Is there anything else which is required to register the samsun-i2s.0 driver ? Can you tell me whether my codec/driver requires any code to register the i2s0 ?

I have the following in my driver : static struct snd_soc_dai_link implant_dai = { .name = "implant bva", .stream_name = "IMPLANT", .cpu_dai_name = "samsung-i2s.0", .codec_dai_name = "implant-pcm", .platform_name = "samsung-i2s.0", .codec_name = "implant-codec", };

thanks Matt

Hi,

Did you set to i2s0 status?

-> status = "okay";

Best regards, Inha Song.

Hi there,

Any ideas why this problem is coming up when I try to load a driver ?

Here is the device tree :

  i2s0: i2s@03830000 {
      compatible = "samsung,i2s-v5";
      reg = <0x03830000 0x100>;
      dmas = <&pdma0 10
          &pdma0 9
          &pdma0 8>;
      dma-names = "tx", "rx", "tx-sec";
      clocks = <&clock_audss EXYNOS_I2S_BUS>,
          <&clock_audss EXYNOS_I2S_BUS>,
          <&clock_audss EXYNOS_SCLK_I2S>;
      clock-names = "iis", "i2s_opclk0", "i2s_opclk1";
      samsung,supports-6ch;
      samsung,supports-rstclr;
      samsung,supports-secdai;
      samsung,idma-addr = <0x03000000>;
      pinctrl-names = "default";
      pinctrl-0 = <&i2s0_bus>;
  };

  implant: implant@0 {
          compatible = "bva,implant";
  };

  sound {
      compatible = "bva,implant-bva";

      samsung,i2s-controller = <&i2s0>;
      samsung,audio-codec = <&implant>;
  };
