1RT5659/RT5658 audio CODEC
2
3This device supports I2C only.
4
5Required 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
13Optional properties:
14
15- clocks: The phandle of the master clock to the CODEC
16- clock-names: Should be "mclk"
17
18- realtek,in1-differential
19- realtek,in3-differential
20- realtek,in4-differential
21  Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended.
22
23- realtek,dmic1-data-pin
24  0: dmic1 is not used
25  1: using IN2N pin as dmic1 data pin
26  2: using GPIO5 pin as dmic1 data pin
27  3: using GPIO9 pin as dmic1 data pin
28  4: using GPIO11 pin as dmic1 data pin
29
30- realtek,dmic2-data-pin
31  0: dmic2 is not used
32  1: using IN2P pin as dmic2 data pin
33  2: using GPIO6 pin as dmic2 data pin
34  3: using GPIO10 pin as dmic2 data pin
35  4: using GPIO12 pin as dmic2 data pin
36
37- realtek,jd-src
38  0: No JD is used
39  1: using JD3 as JD source
40
41- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
42- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
