[v3] Add PCIe RC support to Qcom SDX55 SoC

[PATCH v3 02/13] dt-bindings: PCI: qcom: Add iommu-map properties

Posted by Manivannan Sadhasivam 2 years, 6 months ago

Most of the PCIe controllers require iommu support to function properly.
So let's add the "iommu-map" property that specifies the SMMU SID of the
PCIe devices to the binding.
