VisionFive 2 Board Level Configuration
wm8960 Codec
The file jh7110-visionfive-v2-wm8960.dts stores the wm8960 codec.
For example, the board-level configuration for VisionFive
2 SBC is listed in
the following code block:
/freelight-u-sdk/linux/arch/riscv/boot/dts/starfive/jh7110-visionfive-v2-wm8960.dts /freelight-u-sdk/linux/arch/riscv/boot/dts/starfive/jh7110-visionfive-v2-ac108.dts /freelight-u-sdk/linux/arch/riscv/boot/dts/starfive/codecs/sf_wm8960.dtsi
Note: The codecs file sf_wm8960.dtsi is
used for sound card configuration.
Use the following configuration to connect wm8960 as the
external sound card.
&sound{
/* i2s + wm8960 */
simple-audio-card,dai-link@1 {
reg = <0>;
status = "okay";
format = "i2s";
bitclock-master = <&sndcodec1>;
frame-master = <&sndcodec1>;
widgets =
"Microphone", "Mic Jack",
"Line", "Line In",
"Line", "Line Out",
"Speaker", "Speaker",
"Headphone", "Headphone Jack";
routing =
"Headphone Jack", "HP_L",
"Headphone Jack", "HP_R",
"Speaker", "SPK_LP",
"Speaker", "SPK_LN",
"LINPUT1", "Mic Jack",
"LINPUT3", "Mic Jack",
"RINPUT1", "Mic Jack",
"RINPUT2", "Mic Jack";
cpu0 {
sound-dai = <&i2srx_3ch>;
};
cpu1 {
sound-dai = <&i2stx_4ch1>;
};
sndcodec1:codec {
sound-dai = <&wm8960>;
clocks = <&wm8960_mclk>;
clock-names = "mclk";
};
};
};
ac108 Codec
The jh7110-visionfive-v2-ac108.dts file stores the ac108 codec.
For example, the board-level configuration for VisionFive
2 is listed in the following code block:
/freelight-u-sdk/linux/arch/riscv/boot/dts/starfive/jh7110-visionfive-v2-wm8960.dts /freelight-u-sdk/linux/arch/riscv/boot/dts/starfive/jh7110-visionfive-v2-ac108.dts /freelight-u-sdk/linux/arch/riscv/boot/dts/starfive/codecs/sf_ac108.dtsi
Note: The codecs file
sf_ac108.dtsi is used for sound
card configuration.
Use the following configuration to connect ac108 as the external
sound card.
&sound {
/* i2s + ac108 */
simple-audio-card,dai-link@0 {
reg = <0>;
format = "i2s";
bitclock-master = <&sndcodec1>;
frame-master = <&sndcodec1>;
