From 86d904b6ef9f5e67a28e0a0bb58df898c08ae0b8 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Wed, 10 May 2023 18:03:58 +0900 Subject: [PATCH 1/4] arm64: dts: renesas: Add IOMMU related properties into PCIe host nodes Add iommu-map and iommu-map-mask properties to the PCIe host nodes. Note that iommu-map-mask should be zero because the IPMMU assigns one micro TLB ID only, to the PCIe host. Also change the dma-ranges arguments for IOMMU. Note that dma-ranges can be used if the IOMMU is disabled.
