android dts配置_「7.1」[RK3399][Android7.1] 移植笔记 --- 音频Codec RT5640添加 - seo实验室...

7.1

Platform: RK3399

Kernel: v4.4.83

原理图：

数据走I2S1通道

控制走I2C1通道

输出走HPOUTL/HPOUTR

改动：

DTS配置：

//Kris,180706, porting rt5640 on i2s1.

rt5640-sound {

compatible = "simple-audio-card";

simple-audio-card,format = "i2s";

simple-audio-card,name = "rockchip,rt5640-codec";

simple-audio-card,mclk-fs = <256>;

simple-audio-card,widgets =

"Microphone", "Mic Jack",

"Headphone", "Headphone Jack";

simple-audio-card,routing =

"Mic Jack", "MICBIAS1",

"IN1P", "Mic Jack",

"Headphone Jack", "HPOL",

"Headphone Jack", "HPOR";

simple-audio-card,cpu {

sound-dai = ;

};

simple-audio-card,codec {

sound-dai = ;

};

};

//Kris,180706, porting rt5640 on i2s1.

&i2s1 {

status = "okay";

rockchip,i2s-broken-burst-len;

rockchip,playback-channels = <8>;

rockchip,capture-channels = <8>;

#sound-dai-cells = <0>;

};

&i2c1 {

status = "okay";

i2c-scl-rising-time-ns = <140>;

i2c-scl-falling-time-ns = <30>;

//Kris,180706, porting rt5640 on i2s1.

rt5640: rt5640@1c {

#sound-dai-cells = <0>;

compatible = "realtek,rt5640";

reg = <0x1c>;

clocks = ;

clock-names = "mclk";

realtek,in1-differential;

pinctrl-names = "default";

pinctrl-0 = ;

io-channels = ;

hp-det-adc-value = <500>;

status = "okay";

};

};

由于走的I2S1,所以相应的clock也driver也要修改。
