2
3This device supports I2C only.
4
5Required properties:
6
7- compatible : "realtek,rt5682" or "realtek,rt5682i"
8
9- reg : The I2C address of the device.
10
11- AVDD-supply: phandle to the regulator supplying analog power through the
12  AVDD pin
13
14- MICVDD-supply: phandle to the regulator supplying power for the microphone
15  bias through the MICVDD pin. Either MICVDD or VBAT should be present.
16
17- VBAT-supply: phandle to the regulator supplying battery power through the
18  VBAT pin. Either MICVDD or VBAT should be present.
19
20- DBVDD-supply: phandle to the regulator supplying I/O power through the DBVDD
21  pin.
22
23- LDO1-IN-supply: phandle to the regulator supplying power to the digital core
24  and charge pump through the LDO1_IN pin.
25
26Optional properties:
27
28- interrupts : The CODEC's interrupt output.
29
30- realtek,dmic1-data-pin
31  0: dmic1 is not used
32  1: using GPIO2 pin as dmic1 data pin
33  2: using GPIO5 pin as dmic1 data pin
34
35- realtek,dmic1-clk-pin
36  0: using GPIO1 pin as dmic1 clock pin
37  1: using GPIO3 pin as dmic1 clock pin
38
39- realtek,jd-src
40  0: No JD is used
41  1: using JD1 as JD source
42
43- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
44
45- realtek,btndet-delay
46  The debounce delay for push button.
47  The delay time is realtek,btndet-delay value multiple of 8.192 ms.
48  If absent, the default is 16.
49
50- #clock-cells : Should be set to '<1>',  wclk and bclk sources provided.
51- clock-output-names : Name given for DAI clocks output.
52
53- clocks : phandle and clock specifier for codec MCLK.
54- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
55
56- realtek,dmic-clk-rate-hz : Set the clock rate (hz) for the requirement of
57  the particular DMIC.
58
59- realtek,dmic-delay-ms : Set the delay time (ms) for the requirement of
60  the particular DMIC.
61
62- realtek,dmic-clk-driving-high : Set the high driving of the DMIC clock out.
63
64- #sound-dai-cells: Should be set to '<1>'.
