LoongArch: dts: Add I2S support to Loongson-2K2000
The module is supported, adding it.
Not all Loongson-2K1000 boards have an i2s interface, here is an example
of enabling it:
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>;
};
