RT5665/RT5666/RT5668 audio CODEC
2+
3+
This device supports I2C only.
4+
5+
Required properties:
6+
7+
- compatible : One of "realtek,rt5665", "realtek,rt5666" or "realtek,rt5668".
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+
- 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.
36+
37+
