The module is supported, enable it. Not all Loongson-2K2000 development boards have an i2s interface, here is an example of adding one: sound { compatible = "loongson,ls-audio-card"; model = "Loongson-ASoC"; mclk-fs = <512>; cpu { sound-dai = <&i2s>; }; codec { sound-dai = <&es8323>; }; }; &i2c1 { status = "okay"; #address-cells = <1>; #size-cells = <0>; es8323:es8323@10 { compatible = "everest,es8323"; reg = <0x10>; #sound-dai-cells = <0>; }; }; &i2s { status = "okay"; clock-frequency = <175000000>; #sound-dai-cells = <0>; }; Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> --- arch/loongarch/boot/dts/loongson-2k2000.dtsi | 22 ++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-)
