   1 Freescale i.MX audio complex with SGTL5000 codec
   2
   3 Required properties:
   4
   5   - compatible          : "fsl,imx-audio-sgtl5000"
   6
   7   - model               : The user-visible name of this sound complex
   8
   9   - ssi-controller      : The phandle of the i.MX SSI (or SAI) controller
  10
  11   - audio-codec         : The phandle of the SGTL5000 audio codec
  12
  13   - audio-routing       : A list of the connections between audio components.
  14                           Each entry is a pair of strings, the first being the
  15                           connection's sink, the second being the connection's
  16                           source. Valid names could be power supplies, SGTL5000
  17                           pins, and the jacks on the board:
  18
  19                           Power supplies:
  20                            * Mic Bias
  21
  22                           SGTL5000 pins:
  23                            * MIC_IN
  24                            * LINE_IN
  25                            * HP_OUT
  26                            * LINE_OUT
  27
  28                           Board connectors:
  29                            * Mic Jack
  30                            * Line In Jack
  31                            * Headphone Jack
  32                            * Line Out Jack
  33                            * Ext Spk
  34
  35   - mux-int-port        : The internal port of the i.MX audio muxer (AUDMUX)
  36
  37   - mux-ext-port        : The external port of the i.MX audio muxer
  38
  39 Note: The AUDMUX port numbering should start at 1, which is consistent with
  40 hardware manual.
  41
  42 Optional properties:
  43   - fsl,no-audmux       : boolean
  44                           Required for i.MX6UL (and maybe other SoCs)
  45                           which don't have an AUDMUX, but still
  46                           feature the same audio subsystem otherwise.
  47
  48 Note: Setting this property will make mux-int-port and mux-ext-port
  49 obsolete.

  52 Example:
  53
  54 sound {
  55         compatible = "fsl,imx51-babbage-sgtl5000",
  56                      "fsl,imx-audio-sgtl5000";
  57         model = "imx51-babbage-sgtl5000";
  58         ssi-controller = <&ssi1>;
  59         audio-codec = <&sgtl5000>;
  60         audio-routing =
  61                 "MIC_IN", "Mic Jack",
  62                 "Mic Jack", "Mic Bias",
  63                 "Headphone Jack", "HP_OUT";
  64         mux-int-port = <1>;
  65         mux-ext-port = <3>;
  66 };
  67
  68 or (e.g. for i.MX6UL):
  69 sound {
  70         compatible = "karo,imx6ul-tx6ul-sgtl5000",
  71                      "fsl,imx-audio-sgtl5000";
  72         model = "imx6ul-tx6ul-sgtl5000";
  73         ssi-controller = <&sai2>;
  74         audio-codec = <&sgtl5000>;
  75         audio-routing =
  76                 "MIC_IN", "Mic Jack",
  77                 "Mic Jack", "Mic Bias",
  78                 "Headphone Jack", "HP_OUT";
  79         fsl,no-audmux;
