1RT5650/RT5645 audio CODEC
2
3This device supports I2C only.
4
5Required properties:
6
7- compatible : One of "realtek,rt5645" or "realtek,rt5650".
8
9- reg : The I2C address of the device.
10
11- interrupts : The CODEC's interrupt output.
12
13Optional properties:
14
15- hp-detect-gpios:
16  a GPIO spec for the external headphone detect pin. If jd-mode = 0,
17  we will get the JD status by getting the value of hp-detect-gpios.
18
19- realtek,in2-differential
20  Boolean. Indicate MIC2 input are differential, rather than single-ended.
21
22- realtek,dmic1-data-pin
23  0: dmic1 is not used
24  1: using IN2P pin as dmic1 data pin
25  2: using GPIO6 pin as dmic1 data pin
26  3: using GPIO10 pin as dmic1 data pin
27  4: using GPIO12 pin as dmic1 data pin
28
29- realtek,dmic2-data-pin
30  0: dmic2 is not used
31  1: using IN2N pin as dmic2 data pin
32  2: using GPIO5 pin as dmic2 data pin
33  3: using GPIO11 pin as dmic2 data pin
34
35-- realtek,jd-mode : The JD mode of rt5645/rt5650
36   0 : rt5645/rt5650 JD function is not used
37   1 : Mode-0 (VDD=3.3V), two port jack detection
38   2 : Mode-1 (VDD=3.3V), one port jack detection
39   3 : Mode-2 (VDD=1.8V), one port jack detection
