Subject: [RFC PATCH v2 02/18] iommu/riscv: Move struct riscv_iommu_domain and info to iommu.h
Date: Sat, 20 Sep 2025 15:38:52 -0500	[thread overview]
Message-ID: <20250920203851.2205115-22-ajones@ventanamicro.com> (raw)
In-Reply-To: <20250920203851.2205115-20-ajones@ventanamicro.com>

In order to add the interrupt remapping support in a separate file,
share struct riscv_iommu_domain and struct riscv_iommu_info through
the header.
