iommu/riscv: Add RISC-V IOMMU PCIe device driverIntroduce device driver for PCIe implementationof RISC-V IOMMU architected hardware.IOMMU hardware and system support for MSI or MSI-X isrequired by this implementation.Vendor and device identifiers used in this patchmatches QEMU implementation of the RISC-V IOMMU PCIedevice, from Rivos VID (0x1efd) range allocated by the PCI-SIG.MAINTAINERS | added iommu-pci.c already covered by matching pattern.Link: https://lore.kernel.org/qemu-devel/20240307160319.675044-1-dbarboza@ventanamicro.com/Co-developed-by: Nick Kossifidis Signed-off-by: Nick Kossifidis Reviewed-by: Lu Baolu Signed-off-by: Tomasz Jeznach Acked-by: Palmer Dabbelt Link: https://lore.kernel.org/r/12f3bdbe519ebb7ca482191e7334d38b25b8ae8f.1729059707.git.tjeznach@rivosinc.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/riscv/Makefile

iommu/riscv: Add RISC-V IOMMU platform device driverIntroduce platform device driver for implementation of RISC-V IOMMUarchitected hardware.Hardware interface definition located in file iommu-bits.h is based onratified RISC-V IOMMU Architecture Specification version 1.0.0.This patch implements platform device initialization, early check andconfiguration of the IOMMU interfaces and enables global pass-throughaddress translation mode (iommu_mode == BARE), without registeringhardware instance in the IOMMU subsystem.Link: https://github.com/riscv-non-isa/riscv-iommuCo-developed-by: Nick Kossifidis Signed-off-by: Nick Kossifidis Co-developed-by: Sebastien Boeuf Signed-off-by: Sebastien Boeuf Reviewed-by: Lu Baolu Signed-off-by: Tomasz Jeznach Acked-by: Palmer Dabbelt Link: https://lore.kernel.org/r/2f2e4530c0ee4a81385efa90f1da932f5179f3fb.1729059707.git.tjeznach@rivosinc.comSigned-off-by: Joerg Roedel List of files: /linux-6.15/drivers/iommu/riscv/Makefile
