arm64: dts: socfpga: agilex: add emmc support

2026-01-30T15:44:46+00:00

The Agilex devkit supports a separate eMMC daughter card. The eMMC daughter card replaces the SDMMC slot that is on the default daughter card and thus requires a separate board dts file. Signed-off-by: Ng Tze Yee Signed-off-by: Dinh Nguyen

arm64: dts: intel: agilex5: Add simple-bus node on top of dma controller node

2026-01-30T15:27:12+00:00

Move dma-controller node under simple-bus node to allow bus node specific property able to be properly defined. This is require to fulfill Agilex5 bus limitation that is limited to 40-addressable-bit. Update the compatible string for the DMA controller nodes in the Agilex5 device tree from the generic "snps,axi-dma-1.01a" to the platform-specific "altr,agilex5-axi-dma". Add fallback capability to ensure driver is able to initialize properly. This change enables the use of platform-specific features and constraints in the driver, such as setting a 40-bit DMA addressable mask through dma-ranges, which is required for Agilex5. It also aligns with the updated device tree bindings and driver support for this compatible string. Signed-off-by: Khairul Anuar Romli Signed-off-by: Dinh Nguyen

arm64: dts: altera: Use lowercase hex

2026-01-30T15:27:12+00:00

The DTS code coding style expects lowercase hex for values and unit addresses. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Dinh Nguyen

arm64: dts: socfpga: agilex5: Add IOMMUS property for ethernet nodes

2026-01-30T15:27:12+00:00

To enable SMMU integration, populate the iommus property to the ethernet device-tree node. Signed-off-by: Nazim Amirul Signed-off-by: Dinh Nguyen

arm64: dts: socfpga: agilex5: add support for modular board

2026-01-30T15:27:12+00:00

The Agilex5 Modular board consists of a compute module (Agilex5 SoCFPGA) attached to a carrier board that provides PCIe and additional system interfaces. Signed-off-by: Niravkumar L Rabara Signed-off-by: Dinh Nguyen

arm64: dts: socfpga: agilex5: Add dma-coherent property

2026-01-30T15:27:12+00:00

Add the `dma-coherent` property to these device nodes to inform the kernel and DMA subsystem that the devices support hardware-managed cache coherence. Changes: - Add `dma-coherent` to `cdns,hp-nfc` - Add `dma-coherent` to both `snps,axi-dma-1.01a` instances (dmac0, dmac1) This aligns the Agilex5 device tree with the coherent DMA-capable devices accordingly.

arm64: dts: socfpga: agilex5: update qspi partitions for 013b board

2025-11-17T11:37:59+00:00

Update qspi flash partitions to support Remote System Update (RSU). Signed-off-by: Niravkumar L Rabara Signed-off-by: Dinh Nguyen

arm64: dts: socfpga: add Agilex3 board

2025-11-14T13:00:22+00:00

Agilex3 SoCFPGA development kit is a small form factor board similar to Agilex5 013b board. Agilex3 is derived from Agilex5 SoCFPGA, with the main difference of CPU cores — Agilex3 has 2 cores compared to 4 in Agilex5. Signed-off-by: Niravkumar L Rabara Signed-off-by: Dinh Nguyen

arm64: dts: intel: agilex5: Add Altera compatible for I3C controllers

2025-11-12T18:57:02+00:00

Add the "altr,agilex5-dw-i3c-master" compatible string to the I3C controller nodes on the Agilex5 SoCFPGA platform. Signed-off-by: Adrian Ng Ho Yin Signed-off-by: Dinh Nguyen

arm64: dts: socfpga: Add Agilex5 SVC node with memory region

2025-11-11T03:00:37+00:00

Introduce the Stratix10 SoC Service Layer (SVC) node for Agilex5 SoCs. This node includes the compatible string "intel,agilex5-svc" and references a reserved memory region used for communication with the Secure Device Manager (SDM). Agilex5 introduces changes in how reserved memory is mapped and accessed compared to previous SoC generations. This commit updates the device tree structure to support Agilex5-specific handling of the SVC interface. Signed-off-by: Khairul Anuar Romli Signed-off-by: Dinh Nguyen
