Subject: [PATCH 5/5] iommu/sun50i: Ensure the IOMMU can be used for DMA
Date: Wed, 27 Apr 2022 20:04:00 -0500 [thread overview]
Message-ID: <20220428010401.11323-6-samuel@sholland.org> (raw)
In-Reply-To: <20220428010401.11323-1-samuel@sholland.org>
So far, the driver has relied on arch/arm64/Kconfig to select IOMMU_DMA.
Unsurprisingly, this does not work on RISC-V, so the driver must select
IOMMU_DMA itself.
