RT5682 audio CODEC
|
|
This device supports I2C only.
|
|
Required properties:
|
|
- compatible : "realtek,rt5682" or "realtek,rt5682i"
|
|
- reg : The I2C address of the device.
|
|
Optional properties:
|
|
- interrupts : The CODEC's interrupt output.
|
|
- realtek,dmic1-data-pin
|
0: dmic1 is not used
|
1: using GPIO2 pin as dmic1 data pin
|
2: using GPIO5 pin as dmic1 data pin
|
|
- realtek,dmic1-clk-pin
|
0: using GPIO1 pin as dmic1 clock pin
|
1: using GPIO3 pin as dmic1 clock pin
|
|
- realtek,jd-src
|
0: No JD is used
|
1: using JD1 as JD source
|
|
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
|
|
- realtek,btndet-delay
|
The debounce delay for push button.
|
The delay time is realtek,btndet-delay value multiple of 8.192 ms.
|
If absent, the default is 16.
|
|
- #clock-cells : Should be set to '<1>', wclk and bclk sources provided.
|
- clock-output-names : Name given for DAI clocks output.
|
|
- clocks : phandle and clock specifier for codec MCLK.
|
- clock-names : Clock name string for 'clocks' attribute, should be "mclk".
|
|
- realtek,dmic-clk-rate-hz : Set the clock rate (hz) for the requirement of
|
the particular DMIC.
|
|
- realtek,dmic-delay-ms : Set the delay time (ms) for the requirement of
|
the particular DMIC.
