| Freescale i.MX audio complex with ES8328 codec |
| |
| Required properties: |
| - compatible : "fsl,imx-audio-es8328" |
| - model : The user-visible name of this sound complex |
| - ssi-controller : The phandle of the i.MX SSI controller |
| - jack-gpio : Optional GPIO for headphone jack |
| - audio-amp-supply : Power regulator for speaker amps |
| - audio-codec : The phandle of the ES8328 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, ES8328 |
| pins, and the jacks on the board: |
| |
| Power supplies: |
| * audio-amp |
| |
| ES8328 pins: |
| * LOUT1 |
| * LOUT2 |
| * ROUT1 |
| * ROUT2 |
| * LINPUT1 |
| * LINPUT2 |
| * RINPUT1 |
| * RINPUT2 |
| * Mic PGA |
| |
| Board connectors: |
| * Headphone |
| * Speaker |
| * Mic Jack |
| - 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 (AUDMIX) |
| |
| Note: The AUDMUX port numbering should start at 1, which is consistent with |
| hardware manual. |
| |
| Example: |
| |
| sound { |
| compatible = "fsl,imx-audio-es8328"; |
| model = "imx-audio-es8328"; |
| ssi-controller = <&ssi1>; |
| audio-codec = <&codec>; |
| jack-gpio = <&gpio5 15 0>; |
| audio-amp-supply = <®_audio_amp>; |
| audio-routing = |
| "Speaker", "LOUT2", |
| "Speaker", "ROUT2", |
| "Speaker", "audio-amp", |
| "Headphone", "ROUT1", |
| "Headphone", "LOUT1", |
| "LINPUT1", "Mic Jack", |
| "RINPUT1", "Mic Jack", |
| "Mic Jack", "Mic Bias"; |
| mux-int-port = <1>; |
| mux-ext-port = <3>; |
| }; |
