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.
|
