1 | RT5650/RT5645 audio CODEC |
2 | ||
3 | This device supports I2C only. | |
4 | ||
5 | Required 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 | ||
13 | Optional 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 | |
