Hi,

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

For each patch, the commit message trailer describes its provenance,
keeping tags (incl. Reviewed-by) as-is.

It prepares PCIe EPC-local DMA channels for remote use. For context,
(b) is expected to be superseded by a reworked version of (a):

  (a). vNTB-embedded v1
       https://lore.kernel.org/r/20260312165005.1148676-1-den@valinux.co.jp/
  (b). PCI DMA EPF v7
       https://lore.kernel.org/all/20260813063757.3131865-1-den@valinux.co.jp/

I will post a reworked version of (a) shortly. It will depend on this
small series.

Best regards,
Koichiro
