dmaengine: switchtec-dma: Introduce Switchtec DMA engine skeleton

2026-03-09T07:28:22Z

Some Switchtec Switches can expose DMA engines via extra PCI functions on the upstream ports. At most one such function can be supported on each upstream port. Each function can have one or more DMA channels. This patch is just the core PCI driver skeleton and dma engine registration.

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

2025-09-02T07:07:42Z

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: apple-admac: Drop default ARCH_APPLE in Kconfig

2025-06-17T05:57:41Z

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.
