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.
