Subject: [PATCH v2 0/6] iommu/sun50i: Allwinner D1 support
Date: Mon, 2 Jan 2023 19:08:57 -0600 [thread overview]
Message-ID: <20230103010903.11181-1-samuel@sholland.org> (raw)
D1 is a RISC-V SoC from Allwinner's sunxi family. This series adds IOMMU
binding and driver support. The RISC-V architecture code still needs
some small updates to use an IOMMU for DMA[1][2]. I will send those
separately.

[2]: https://lore.kernel.org/linux-riscv/7b09e989-0aa1-a557-485e-572f69caf881@arm.com/
Changes in v2:
- Disallow the 'resets' property for the D1 variant
- Set bypass based on attached devices instead of using a fixed value
Samuel Holland (6):
dt-bindings: iommu: sun50i: Add compatible for Allwinner D1
iommu/sun50i: Track masters attached to the domain
iommu/sun50i: Keep the bypass register up to date
iommu/sun50i: Support variants without an external reset
iommu/sun50i: Add support for the D1 variant
riscv: dts: allwinner: d1: Add the IOMMU node
