dmaengine: bcm2835: enable compile testing

2025-11-21T12:13:21+00:00

There seems to be nothing preventing the driver from being compile tested so enable that for wider build coverage. Signed-off-by: Johan Hovold Link: https://patch.msgid.link/20251120115016.8967-1-johan@kernel.org Signed-off-by: Vinod Koul

dmaengine: at_hdmac: add COMPILE_TEST support

dmaengine: mmp_pdma: Add SpacemiT K1 PDMA support with 64-bit addressing

2025-09-02T07:07:42+00:00

Add support for SpacemiT K1 PDMA controller which features 64-bit addressing capabilities. The SpacemiT K1 PDMA extends the descriptor format with additional 32-bit words for high address bits, enabling access to memory beyond 4GB boundaries. The new spacemit_k1_pdma_ops provides necessary 64-bit address handling functions and k1 specific controller configurations. Key changes: - Add ARCH_SPACEMIT dependency to Kconfig - Define new high 32-bit address registers (DDADRH, DSADRH, DTADRH) - Add DCSR_LPAEEN bit for Long Physical Address Extension Enable - Implement 64-bit operations for SpacemiT K1 PDMA Signed-off-by: Guodong Xu Link: https://lore.kernel.org/r/20250822-working_dma_0701_v2-v5-5-f5c0eda734cc@riscstar.com Signed-off-by: Vinod Koul

dmaengine: xdmac: make it selectable for ARCH_MICROCHIP

2025-07-23T12:25:32+00:00

LAN969x uses the Atmel XDMAC, so make it selectable for ARCH_MICROCHIP to avoid needing to update depends in future if other Microchip SoC-s use it as well. Signed-off-by: Robert Marko Link: https://lore.kernel.org/r/20250702183856.1727275-9-robert.marko@sartura.hr Signed-off-by: Vinod Koul

dmaengine: apple-admac: Drop default ARCH_APPLE in Kconfig

2025-06-17T05:57:41+00:00

When the first driver for Apple Silicon was upstreamed we accidentally included `default ARCH_APPLE` in its Kconfig which then spread to almost every subsequent driver. As soon as ARCH_APPLE is set to y this will pull in many drivers as built-ins which is not what we want. Thus, drop `default ARCH_APPLE` from Kconfig.

dmaengine: add driver for Sophgo CV18XX/SG200X dmamux

2025-06-17T05:56:13+00:00

Sophgo CV18XX/SG200X use DW AXI CORE with a multiplexer for remapping its request lines. The multiplexer supports at most 8 request lines. Add driver for Sophgo CV18XX/SG200X DMA multiplexer.

dmaengine: ARM_DMA350 should depend on ARM/ARM64

2025-04-23T13:12:46+00:00

The Arm DMA-350 controller is only present on Arm-based SoCs. Hence add dependencies on ARM and ARM64, to prevent asking the user about this driver when configuring a kernel for a non-Arm architecture.

dmaengine: Add Arm DMA-350 driver

2025-04-17T15:17:39+00:00

Add an initial driver for the Arm Corelink DMA-350 controller, to support basic mem-to-mem async_tx. The design here leaves room for more fun things like peripheral support and scatter-gather chaining to come in future.

DMA of Allwinner suniv F1C100s is similar to sun4i. It has 4 NDMA, 4 DDMA channels and endpoints are different. Also F1C100s has reset bit for DMA in CCU. Add support for it.
