Subject: [PATCH v3 4/5] arm64: dts: rockchip: Add verisilicon IOMMU node on RK3588
Date: Thu, 19 Jun 2025 15:12:25 +0200 [thread overview]
Message-ID: <20250619131232.69208-5-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20250619131232.69208-1-benjamin.gaignard@collabora.com>
Add the device tree node for the Verisilicon IOMMU present
in the RK3588 SoC.
This IOMMU handles address translation for the VPU hardware blocks.
