+	 *  HiSilicon erratum 161010801: This describes the limitation
+	 *  of HiSilicon platforms hip06/hip07 to support the SMMUv3
+	 *  mappings for PCIe MSI transactions.
+	 *  PCIe controller on these platforms has to differentiate the
+	 *  MSI payload against other DMA payload and has to modify the
+	 *  MSI payload. This makes it difficult for these platforms to
+	 *  have a SMMU translation for MSI. In order to workaround this,
+	 *  ARM SMMUv3 driver requires a quirk to treat the MSI regions
+	 *  separately. Such a quirk is currently missing for DT based
+	 *  systems. Hence please make sure that the smmu pcie node on
+	 *  hip07 is disabled as this will break the PCIe functionality
+	 *  when iommu-map entry is used along with the PCIe node.
+	 *  Refer:https://www.spinics.net/lists/arm-kernel/msg602812.html
