Subject: [PATCH] iommu: ipmmu-vmsa: Add DMA controllers to devices_allowlist
Date: Mon, 27 Oct 2025 09:48:16 +0900 [thread overview]
Message-ID: <20251027004816.562965-1-den@valinux.co.jp> (raw)
Add Renesas DMA controller devices to the devices_allowlist to enable
their use with the IPMMU. This allows DMA channels to operate through
the IOMMU when enabled.
