Hi Linus,
Please pull to receive dmaengine updates which consist of a new core
api, a new Mediatek device support and updates led by dw-dma driver and
few others.
The following changes since commit dc59e4fea9d83f03bad6bddf3fa2e52491777482:
Linux 7.2-rc1 (2026-06-28 12:01:31 -0700)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine.git tags/dmaengine-7.3-rc1

dmaengine: dw-edma: Mark emulated IRQ as level-triggered (2026-08-12 00:16:54 +0530)
----------------------------------------------------------------
dmaengine updates for v7.3
Core:
- New API to combine configuration and preparation and users
New Support:
- Mediatek MT8189 SoC uart dma support
Updates:
- Designware dma driver flatten desc structures and simplify code,
interrupt-path groundwork changes, first part of PCI EP DMA support
- Updates to zynqmp_dma with runtime PM and device removal improvments
- Xilinx dma optimizations for AXIDMA and MCDMA channel management
