900f6267e9 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>;
};

7c33c9111c LoongArch: dts: Add new supported device nodes to Loongson-2K2000
By now, more Loongson-2K2000 related drivers are supported, such as
clock controller and thermal controller. So we add these device nodes
to the Loongson-2K2000 dts file.

84892cebdc LoongArch: Update dts for Loongson-2K2000 to support PCI-MSI
Current dts file for Loongson-2K2000 misses the interrupt-controller &
interrupt-cells descriptions in the msi-controller node, and misses the
msi-parent link in the pci root node. Add them to support PCI-MSI.

b07b9f353d LoongArch: Update dts for Loongson-2K2000 to support ISA/LPC
Some Loongson-2K2000 platforms have ISA/LPC devices such as Super-IO,
define an ISA node in the dts file to avoid access error. Also adjust
the PCI io resource range to avoid confliction.
