[PATCH 0/4] RISC-V: Add ACPI support for IOMMU

[Sunil V L]

This series adds support for RISC-V IOMMU on ACPI based platforms.
RISC-V IO Mapping Table (RIMT) is a new static ACPI table [1] introduced
to communicate IOMMU information to the OS.

The first patch in the series is a ACPICA patch which is already
available in linux-next but included in this series for completeness
only.
