Kernel-4.18.0-80.el8_imx-audio-sgtl5000

Freescale i.MX audio complex with SGTL5000 codec

Required properties:

• compatible : “fsl,imx-audio-sgtl5000”

• model : The user-visible name of this sound complex

• ssi-controller : The phandle of the i.MX SSI controller

• audio-codec : The phandle of the SGTL5000 audio codec

• audio-routing : A list of the connections between audio components.

        Each entry is a pair of strings, the first being the
        connection's sink, the second being the connection's
        source. Valid names could be power supplies, SGTL5000
        pins, and the jacks on the board:
  
        Power supplies:
         * Mic Bias
  
        SGTL5000 pins:
         * MIC_IN
         * LINE_IN
         * HP_OUT
         * LINE_OUT
  
        Board connectors:
         * Mic Jack
         * Line In Jack
         * Headphone Jack
         * Line Out Jack
         * Ext Spk
  

• mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)

• mux-ext-port : The external port of the i.MX audio muxer

Note: The AUDMUX port numbering should start at 1, which is consistent with
hardware manual.

Example:

sound {
compatible = “fsl,imx51-babbage-sgtl5000”,
“fsl,imx-audio-sgtl5000”;
model = “imx51-babbage-sgtl5000”;
ssi-controller = <&ssi1>;
audio-codec = <&sgtl5000>;
audio-routing =
“MIC_IN”, “Mic Jack”,
“Mic Jack”, “Mic Bias”,
“Headphone Jack”, “HP_OUT”;
mux-int-port = <1>;
mux-ext-port = <3>;
};
