RT5660 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5660".
- reg : The I2C address of the device.
Optional properties:
- clocks: The phandle of the master clock to the CODEC
- clock-names: Should be "mclk"
- realtek,in1-differential
- realtek,in3-differential
Boolean. Indicate MIC1/3 input are differential, rather than single-ended.
- realtek,poweroff-in-suspend
Boolean. If the codec will be powered off in suspend, the resume should be
added delay time for waiting codec power ready.
- realtek,dmic1-data-pin
0: dmic1 is not used
1: using GPIO2 pin as dmic1 data pin
2: using IN1P pin as dmic1 data pin
