Subject: [PATCH 0/3] Rockchip IOMMU fixes
Date: Thu, 13 Mar 2025 17:31:03 +0000	[thread overview]
Message-ID: <cover.1741886382.git.robin.murphy@arm.com> (raw)

Hi all,

I was expecting my DT probing change to flush out issues, and it seems
some weaknesses in rockchip-iommu were the first to show. The first two
patches here get things working again for me on my RK3399 NanoPC-T4
(with a console on HDMI exercising the VOP MMU), the 3rd patch just
finishes the cleanup since I was there and could test it.

Thanks,
Robin.

  iommu/rockchip: Allocate per-device data sensibly
  iommu/rockchip: Register in a sensible order
  iommu/rockchip: Retire global dma_dev workaround
