RT5668B audio CODEC
|
||
|
|
|
||
|
|
This device supports I2C only.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : "realtek,rt5668b"
|
||
|
|
|
||
|
|
- reg : The I2C address of the device.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
|
||
|
|
- interrupts : The CODEC's interrupt output.
|
||
|
|
|
||
|
|
- realtek,dmic1-data-pin
|
||
|
|
0: dmic1 is not used
|
||
|
|
1: using GPIO2 pin as dmic1 data pin
|
||
|
|
2: using GPIO5 pin as dmic1 data pin
|
||
|
|
|
||
|
|
- realtek,dmic1-clk-pin
|
||
|
|
0: using GPIO1 pin as dmic1 clock pin
|
||
|
|
1: using GPIO3 pin as dmic1 clock pin
|
||
|
|
|
||
|
|
- realtek,jd-src
|
||
|
|
0: No JD is used
|
||
|
|
1: using JD1 as JD source
|
||
|
|
|
||
|
|
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
|
||
|
|
|
||
|
|
