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  2: JD source for Intel HDA header
41
42- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
43- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
44
45- sound-name-prefix: Please refer to name-prefix.yaml
46
47- ports: A Codec may have a single or multiple I2S interfaces. These
48  interfaces on Codec side can be described under 'ports' or 'port'.
49  When the SoC or host device is connected to multiple interfaces of
50  the Codec, the connectivity can be described using 'ports' property.
51  If a single interface is used, then 'port' can be used. The usage
52  depends on the platform or board design.
