1 | RT5659/RT5658 audio CODEC |
2 | ||
3 | This device supports I2C only. | |
4 | ||
5 | Required properties: | |
6 | ||
7 | - compatible : One of "realtek,rt5659" or "realtek,rt5658". | |
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,in3-differential | |
17 | - realtek,in4-differential | |
18 | Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended. | |
19 | ||
20 | - realtek,dmic1-data-pin | |
21 | 0: dmic1 is not used | |
22 | 1: using IN2N pin as dmic1 data pin | |
23 | 2: using GPIO5 pin as dmic1 data pin | |
24 | 3: using GPIO9 pin as dmic1 data pin | |
25 | 4: using GPIO11 pin as dmic1 data pin | |
26 | ||
27 | - realtek,dmic2-data-pin | |
28 | 0: dmic2 is not used | |
29 | 1: using IN2P pin as dmic2 data pin | |
30 | 2: using GPIO6 pin as dmic2 data pin | |
31 | 3: using GPIO10 pin as dmic2 data pin | |
32 | 4: using GPIO12 pin as dmic2 data pin | |
33 | ||
34 | - realtek,jd-src | |
35 | 0: No JD is used | |
36 | 1: using JD3 as JD source | |
37 | ||
38 | - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. | |
39 | - realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin. | |
