Freescale Generic ASoC Sound Card with ASRC support
|
||||
|
||||
The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
|
||||
SoCs connecting with external CODECs.
|
||||
|
||||
The idea of this generic sound card is a bit like ASoC Simple Card. However,
|
||||
for Freescale SoCs (especially those released in recent years), most of them
|
||||
have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
|
||||
this is a specific feature that might be painstakingly controlled and merged
|
||||
into the Simple Card.
|
||||
|
||||
So having this generic sound card allows all Freescale SoC users to benefit
|
||||
from the simplification of a new card support and the capability of the wide
|
||||
sample rates support through ASRC.
|
||||
|
||||
Note: The card is initially designed for those sound cards who use I2S and
|
||||
PCM DAI formats. However, it'll be also possible to support those non
|
||||
I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as long
|
||||
as the driver has been properly upgraded.
|
||||
|
||||
|
||||
The compatible list for this generic sound card currently:
|
||||
"fsl,imx-audio-cs42888"
|
||||
|
||||
"fsl,imx-audio-wm8962"
|
||||
(compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)
|
||||
|
||||
"fsl,imx-audio-sgtl5000"
|
||||
(compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : Contains one of entries in the compatible list.
|
||||
|
||||
- model : The user-visible name of this sound complex
|
||||
|
||||
- audio-cpu : The phandle of an CPU DAI controller
|
||||
|
||||
- audio-codec : The phandle of an 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. There're a few pre-designed board connectors:
|
||||
* Line Out Jack
|
||||
* Line In Jack
|
||||
* Headphone Jack
|
||||
* Mic Jack
|
||||
* Ext Spk
|
||||
* AMIC (stands for Analog Microphone Jack)
|
||||
* DMIC (stands for Digital Microphone Jack)
|
||||
|
||||
Note: The "Mic Jack" and "AMIC" are redundant while
|
||||
coexsiting in order to support the old bindings
|
||||
of wm8962 and sgtl5000.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- audio-asrc : The phandle of ASRC. It can be absent if there's no
|
||||
need to add ASRC support via DPCM.
|
||||
|
||||
Example:
|
||||
sound-cs42888 {
|
||||
compatible = "fsl,imx-audio-cs42888";
|
||||
model = "cs42888-audio";
|
||||
audio-cpu = <&esai>;
|
||||
audio-asrc = <&asrc>;
|
||||
audio-codec = <&cs42888>;
|
||||
audio-routing =
|
||||
"Line Out Jack", "AOUT1L",
|
||||
"Line Out Jack", "AOUT1R",
|
||||
"Line Out Jack", "AOUT2L",
|
||||
"Line Out Jack", "AOUT2R",
|
||||
"Line Out Jack", "AOUT3L",
|
||||
"Line Out Jack", "AOUT3R",
|
||||
"Line Out Jack", "AOUT4L",
|
||||
"Line Out Jack", "AOUT4R",
|
||||
"AIN1L", "Line In Jack",
|
||||
"AIN1R", "Line In Jack",
|
||||
"AIN2L", "Line In Jack",
|
||||
"AIN2R", "Line In Jack";
|
||||
};
