| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | Freescale i.MX audio complex with ES8328 codec |
| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "fsl,imx-audio-es8328" |
| 5 | - model : The user-visible name of this sound complex |
| 6 | - ssi-controller : The phandle of the i.MX SSI controller |
| 7 | - jack-gpio : Optional GPIO for headphone jack |
| 8 | - audio-amp-supply : Power regulator for speaker amps |
| 9 | - audio-codec : The phandle of the ES8328 audio codec |
| 10 | - audio-routing : A list of the connections between audio components. |
| 11 | Each entry is a pair of strings, the first being the |
| 12 | connection's sink, the second being the connection's |
| 13 | source. Valid names could be power supplies, ES8328 |
| 14 | pins, and the jacks on the board: |
| 15 | |
| 16 | Power supplies: |
| 17 | * audio-amp |
| 18 | |
| 19 | ES8328 pins: |
| 20 | * LOUT1 |
| 21 | * LOUT2 |
| 22 | * ROUT1 |
| 23 | * ROUT2 |
| 24 | * LINPUT1 |
| 25 | * LINPUT2 |
| 26 | * RINPUT1 |
| 27 | * RINPUT2 |
| 28 | * Mic PGA |
| 29 | |
| 30 | Board connectors: |
| 31 | * Headphone |
| 32 | * Speaker |
| 33 | * Mic Jack |
| 34 | - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX) |
| 35 | - mux-ext-port : The external port of the i.MX audio muxer (AUDMIX) |
| 36 | |
| 37 | Note: The AUDMUX port numbering should start at 1, which is consistent with |
| 38 | hardware manual. |

| 40 | Example: |
| 41 | |
| 42 | sound { |
| 43 | compatible = "fsl,imx-audio-es8328"; |
| 44 | model = "imx-audio-es8328"; |

| 47 | jack-gpio = <&gpio5 15 0>; |
| 48 | audio-amp-supply = <®_audio_amp>; |
| 49 | audio-routing = |

| 51 | "Speaker", "ROUT2", |
| 52 | "Speaker", "audio-amp", |
| 53 | "Headphone", "ROUT1", |
| 54 | "Headphone", "LOUT1", |
| 55 | "LINPUT1", "Mic Jack", |
| 56 | "RINPUT1", "Mic Jack", |
| 57 | "Mic Jack", "Mic Bias"; |
| 58 | mux-int-port = <1>; |
| 59 | mux-ext-port = <3>; |
| 60 | }; |
