- compatible : should be "realtek,rtl-8125"

If SMMU is present, also use:

- qcom,smmu : if present, SMMU attach is performed
- qcom,smmu-iova-base : SMMU IOVA start address the device can access
- qcom,smmu-iova-size : SMMU IOVA size the device can access

Optional Properties:

- qcom,smmu-attr-fastmap : Enables SMMU fastmap
- qcom,smmu-attr-atomic : Enables DMA alloc using GFP_ATOMIC

Example:

&pcie_rc0 {

	r8125_x1: qcom,r8125@0 {
		compatible = realtek,rtl-8125";

		qcom,smmu;
		qcom,smmu-iova-base = /bits/ 64 <0x0>;
		qcom,smmu-iova-size = /bits/ 64 <0x100000000>;

		qcom,smmu-attr-atomic;
		qcom,smmu-attr-fastmap;
	};
};
