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;
};
Everest ES8328 audio CODEC
This device supports both I2C and SPI.
Required properties:
- compatible : "everest,es8328"
- DVDD-supply : Regulator providing digital core supply voltage 1.8 - 3.6V
- AVDD-supply : Regulator providing analog supply voltage 3.3V
- PVDD-supply : Regulator providing digital IO supply voltage 1.8 - 3.6V
- IPVDD-supply : Regulator providing analog output voltage 3.3V
- clocks : A 22.5792 or 11.2896 MHz clock
- reg : the I2C address of the device for I2C, the chip select number for SPI
Pins on the device (for linking into audio routes):
* LOUT1
* LOUT2
* ROUT1
* ROUT2
* LINPUT1
* RINPUT1
* LINPUT2
* RINPUT2
* Mic Bias
Example:
codec: es8328@11 {
compatible = "everest,es8328";
DVDD-supply = <&reg_3p3v>;
AVDD-supply = <&reg_3p3v>;
PVDD-supply = <&reg_3p3v>;
HPVDD-supply = <&reg_3p3v>;
clocks = <&clks 169>;
reg = <0x11>;
};
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 =

- pinctrl-names: Must contain a "default" entry.
- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
See ../pinctrl/pinctrl-bindings.txt for details of the property values.

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.
Example:
sound {
compatible = "fsl,imx-audio-es8328";
model = "imx-audio-es8328";
