1RT5682 audio CODEC
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
11Optional properties:
12
13- interrupts : The CODEC's interrupt output.
14
15- realtek,dmic1-data-pin
16  0: dmic1 is not used
17  1: using GPIO2 pin as dmic1 data pin
18  2: using GPIO5 pin as dmic1 data pin
19
20- realtek,dmic1-clk-pin
21  0: using GPIO1 pin as dmic1 clock pin
22  1: using GPIO3 pin as dmic1 clock pin
23
24- realtek,jd-src
25  0: No JD is used
26  1: using JD1 as JD source
27
28- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
29
30- realtek,btndet-delay
31  The debounce delay for push button.
32  The delay time is realtek,btndet-delay value multiple of 8.192 ms.
33  If absent, the default is 16.
34
35- #clock-cells : Should be set to '<1>',  wclk and bclk sources provided.
36- clock-output-names : Name given for DAI clocks output.
37
38- clocks : phandle and clock specifier for codec MCLK.
39- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
40
41- realtek,dmic-clk-rate-hz : Set the clock rate (hz) for the requirement of
42  the particular DMIC.
43
44- realtek,dmic-delay-ms : Set the delay time (ms) for the requirement of
45  the particular DMIC.
