1	RT5640/RT5639 audio CODEC
2	
3	This device supports I2C only.
4	
5	Required properties:
6	
7	- compatible : One of "realtek,rt5640" or "realtek,rt5639".
8	
9	- reg : The I2C address of the device.
10	
11	- interrupts : The CODEC's interrupt output.
12	
13	Optional properties:
14	
15	- realtek,in1-differential
16	- realtek,in2-differential
17	  Boolean. Indicate MIC1/2 input are differential, rather than single-ended.
18	
19	- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
