The module is supported, enable it. Not all Loongson-2K1000 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 = <&uda1342>; }; }; &apbdma2 { status = "okay"; }; &apbdma3 { status = "okay"; }; &i2c3 { status = "okay"; pinctrl-0 = <&i2c1_pins_default>; pinctrl-names = "default"; #address-cells = <1>; #size-cells = <0>; uda1342: codec@1a { compatible = "nxp,uda1342"; reg = <0x1a>; #sound-dai-cells = <0>; }; }; &i2s { status = "okay"; pinctrl-0 = <&hda_pins_default>; pinctrl-names = "default"; }; Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> --- arch/loongarch/boot/dts/loongson-2k1000.dtsi | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-)
