1RT5640/RT5639 audio CODEC
2
3This device supports I2C only.
4
5Required 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
13Optional properties:
14
15- realtek,in1-differential
16- realtek,in2-differential
17  Boolean. Indicate MIC1/2 input are differential, rather than single-ended.
