RT5659/RT5658 audio CODEC
|
||
|
|
|
||
|
|
This device supports I2C only.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : One of "realtek,rt5659" or "realtek,rt5658".
|
||
|
|
|
||
|
|
- reg : The I2C address of the device.
|
||
|
|
|
||
|
|
- interrupts : The CODEC's interrupt output.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
|
||
|
|
- clocks: The phandle of the master clock to the CODEC
|
||
|
|
- clock-names: Should be "mclk"
|
||
|
|
|
||
|
|
- realtek,in1-differential
|
||
|
|
- realtek,in3-differential
|
||
|
|
- realtek,in4-differential
|
||
|
|
Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended.
|
||
|
|
|
||
|
|
- realtek,dmic1-data-pin
|
||
|
|
0: dmic1 is not used
|
||
|
|
1: using IN2N pin as dmic1 data pin
|
||
|
|
2: using GPIO5 pin as dmic1 data pin
|
||
|
|
3: using GPIO9 pin as dmic1 data pin
|
||
|
|
4: using GPIO11 pin as dmic1 data pin
|
||
|
|
|
||
|
|
- realtek,dmic2-data-pin
|
||
|
|
0: dmic2 is not used
|
||
|
|
1: using IN2P pin as dmic2 data pin
|
||
|
|
2: using GPIO6 pin as dmic2 data pin
|
||
|
|
3: using GPIO10 pin as dmic2 data pin
|
||
|
|
4: using GPIO12 pin as dmic2 data pin
|
||
|
|
|
||
|
|
- realtek,jd-src
|
||
|
|
0: No JD is used
|
||
|
|
1: using JD3 as JD source
|
||
|
|
2: JD source for Intel HDA header
|
||
|
|
|
||
|
|
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
|
||
|
|
- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
|
||
|
|
|
||
|
|
- sound-name-prefix: Please refer to name-prefix.txt
|
||
|
|
|
||
|
|
- ports: A Codec may have a single or multiple I2S interfaces. These
|
||
|
|
interfaces on Codec side can be described under 'ports' or 'port'.
|
||
|
|
When the SoC or host device is connected to multiple interfaces of
|
||
|
|
the Codec, the connectivity can be described using 'ports' property.
|
||
|
|
If a single interface is used, then 'port' can be used. The usage
|
||
|
|
depends on the platform or board design.
|
||
