[PATCH 0/4] dmaengine: dw-edma: Fix probe paths and register races

Posted by Koichiro Den 3 days, 5 hours ago

Hi,

This series fixes pre-existing dw-edma issues flagged by Sashiko in:
https://lore.kernel.org/dmaengine/20260521063115.2842238-1-den@valinux.co.jp/

Note: Patch 4 was based on a patch Frank posted in January:
      https://lore.kernel.org/dmaengine/20260109-edma_ll-v2-1-5c0b27b2c664@nxp.com/
      Since it has not been merged, I included it here. Frank, please let me
      know if you prefer a different handling.

Best regards,
Koichiro
