Aquantia Corporation AQC/AQN 107/108/109 Ethernet Controller


Required properties:

- compatible : should be one of "aquantia,aqc-107", "aquantia,aqc-108",
  "aquantia,aqc-109"

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-s1-bypass : Bypasses SMMU S1 translation
- qcom,smmu-attr-fastmap : Enables SMMU fastmap
- qcom,smmu-attr-atomic : Enables DMA alloc using GFP_ATOMIC
- qcom,smmu-attr-pt-coherent : Use if DMA coherency is available for SMMU page tables


Example:

&pcie_rc0 {

	aqc_x1: qcom,aqc@0 {
		compatible = "aquantia,aqc-107";

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

		qcom,smmu-attr-s1-bypass;
	};
};

&pcie_rc1 {

	aqc_x4: qcom,aqc@1 {
		compatible = "aquantia,aqc-107";

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

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