dt-bindings: Updates Linus Walleij's mail address

2025-12-16T16:17:59+00:00

My name is stamped into maintainership for a big slew of DT bindings. Now that it is changing, switch it over to my kernel.org mail address, which will hopefully be stable for the rest of my life.

dt-bindings: dma: xilinx: Simplify dma-coherent property

2025-11-21T12:15:04+00:00

Common boolean properties need to be only allowed in the binding (":true"), because their type is already defined by core DT schema. Simplify dma-coherent property to match common syntax.

dt-bindings: dma: allwinner,sun50i-a64-dma: Add compatibles for A523

2025-10-28T17:07:33+00:00

There are two DMA controllers on the A523, one in the main system area and the other for the MCU. These are the same as the one found on the A100. The only difference is the DMA endpoint (DRQ) layout. Since the number of channels and endpoints are described with additional generic properties, just add new A523-specific compatible strings and fallback to the A100 one.

dt-bindings: dma: snps,dw-axi-dmac: Add iommu property

2025-10-20T15:20:53+00:00

Agilex5 integrates an ARM SMMU v3 (System Memory Management Unit) with dedicated Translation Buffer Units (TBUs) assigned to various peripherals, including the Synopsys DesignWare AXI DMA controller. Each TBU handles address translation for its associated device by mapping stream IDs to memory access permissions and virtual-to-physical address mappings via the SMMU core. The DesignWare AXI DMAC instances on Agilex5 are connected to their respective TBUs. These TBUs forward DMA transactions from the controller through the SMMU, enabling IOMMU-based features such as: - Address translation for DMA operations - Isolation and protection of memory regions accessed by the DMA controller - Support for secure and virtualized environments through enforced access control To support this configuration, the `iommus` property must be added to the binding schema for `snps,dw-axi-dmac`. This allows the device tree to associate each DMA controller with the correct SMMU stream ID, enabling the Linux IOMMU framework to configure translation contexts at runtime. This change documents the IOMMU support for the DMA controller on Agilex5 and allows proper integration with the SMMUv3 hardware.
