Device-Tree binding for regmap
|
||||||
|
|
||||||
|
The endianness mode of CPU & Device scenarios:
|
||||||
|
Index Device Endianness properties
|
||||||
|
---------------------------------------------------
|
||||||
|
1 BE 'big-endian'
|
||||||
|
2 LE 'little-endian'
|
||||||
|
|
||||||
|
For one device driver, which will run in different scenarios above
|
||||||
|
on different SoCs using the devicetree, we need one way to simplify
|
||||||
|
this.
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- {big,little}-endian: these are boolean properties, if absent
|
||||||
|
meaning that the CPU and the Device are in the same endianness mode,
|
||||||
|
these properties are for register values and all the buffers only.
|
||||||
|
|
||||||
|
Examples:
|
||||||
|
Scenario 1 : CPU in LE mode & device in LE mode.
|
||||||
|
dev: dev@40031000 {
|
||||||
|
compatible = "name";
|
||||||
|
reg = <0x40031000 0x1000>;
|
||||||
|
...
|
||||||
|
};
|
||||||
|
|
||||||
|
Scenario 2 : CPU in LE mode & device in BE mode.
|
||||||
|
dev: dev@40031000 {
|
||||||
|
compatible = "name";
|
||||||
|
reg = <0x40031000 0x1000>;
|
||||||
|
...
|
||||||
|
big-endian;
|
||||||
|
};
|
||||||
|
|
||||||
|
Scenario 3 : CPU in BE mode & device in BE mode.
|
||||||
|
dev: dev@40031000 {
|
||||||
|
compatible = "name";
|
||||||
|
reg = <0x40031000 0x1000>;
|
||||||
|
...
|
||||||
|
};
|
||||||
|
|
||||||
|
Scenario 4 : CPU in BE mode & device in LE mode.
|
||||||
|
dev: dev@40031000 {
|
||||||
|
compatible = "name";
|
||||||
|
reg = <0x40031000 0x1000>;
|
||||||
|
...
|
||||||
|
little-endian;

|
};

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.
|
||||||
|
|
||||||
|

|
||||||
|
sound-cs42888 {
|
||||||
