[PATCH v10 6/7] arm64: dts: rockchip: Add verisilicon IOMMU node on RK3588

From: Benjamin Gaignard <benjamin.gaignard@collabora.com>
Date: 2025-12-15 08:54:00
Also in: linux-arm-kernel, linux-iommu, linux-media, linux-rockchip, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

Add the device tree node for the Verisilicon IOMMU present
in the RK3588 SoC.
This IOMMU handles address translation for the VPU hardware blocks.
