| Freescale i.MX audio complex with WM8962 codec |
| |
| Required properties: |
| |
| - compatible : "fsl,imx-audio-wm8962" |
| |
| - model : The user-visible name of this sound complex |
| |
| - cpu-dai : The phandle of CPU DAI |
| |
| - audio-codec : The phandle of the WM8962 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, WM8962 |
| pins, and the jacks on the board: |
| |
| Power supplies: |
| * Mic Bias |
| |
| Board connectors: |
| * Mic Jack |
| * Headphone 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. |
| |
| Optional properties: |
| - hp-det-gpios : The gpio pin to detect plug in/out event that happens to |
| Headphone jack. |
| - mic-det-gpios: The gpio pin to detect plug in/out event that happens to |
| Microphone jack. |
| |
| Example: |
| |
| sound { |
| compatible = "fsl,imx6q-sabresd-wm8962", |
| "fsl,imx-audio-wm8962"; |
| model = "wm8962-audio"; |
| cpu-dai = <&ssi2>; |
| audio-codec = <&codec>; |
| audio-routing = |
| "Headphone Jack", "HPOUTL", |

| "Ext Spk", "SPKOUTL", |
| "Ext Spk", "SPKOUTR", |
| "MICBIAS", "AMIC", |
| "IN3R", "MICBIAS", |
| "DMIC", "MICBIAS", |
| "DMICDAT", "DMIC"; |
| mux-int-port = <2>; |
| mux-ext-port = <3>; |
| hp-det-gpios = <&gpio7 8 1>; |
| mic-det-gpios = <&gpio1 9 1>; |
| }; |
