1RT5665/RT5666 audio CODEC
2
3This device supports I2C only.
4
5Required properties:
6
7- compatible : One of "realtek,rt5665", "realtek,rt5666".
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- realtek,in3-differential
18- realtek,in4-differential
19  Boolean. Indicate MIC1/2/3/4 input are differential, rather than single-ended.
20
21- realtek,dmic1-data-pin
22  0: dmic1 is not used
23  1: using GPIO4 pin as dmic1 data pin
24  2: using IN2N pin as dmic2 data pin
25
26- realtek,dmic2-data-pin
27  0: dmic2 is not used
28  1: using GPIO5 pin as dmic2 data pin
29  2: using IN2P pin as dmic2 data pin
30
31- realtek,jd-src
32  0: No JD is used
33  1: using JD1 as JD source
34
35- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
