Hi,

This small series contains standalone refactoring and new infrastructure
for dmaengine and dw-edma.

It prepares PCIe EPC-local DMA channels for remote use. The upcoming
vNTB-embedded DMA support [1] will be the first user and depend on this
series.

    (This is v3. I will send v4 shortly.)

Best regards,
Koichiro

Changes in v3:
  - Rework patch 2 to use a common channel configuration, retain generic
    dma_slave_config fields, and close the shared-IRQ routing race.
    (Frank, Sashiko)
  - No code changes in patches 1 and 3.

Changes in v2:
  - Split and rework vNTB v1 patches 1, 4, and 5 into this prerequisite
    series.
  - Fold in the relevant PCI DMA EPF v7 review.

v2: https://lore.kernel.org/r/20260828163611.2691264-1-den@valinux.co.jp/
v1: https://lore.kernel.org/r/20260312165005.1148676-1-den@valinux.co.jp/
