Subject: [PATCH 0/3] dmaengine: dw-axi-dmac: fix termination and pause acknowledgment
Date: Sun, 08 Nov 2026 22:02:35 -0700 [thread overview]
Message-ID: <20261108-submit-dw-axi-dma-stop-pause-v1-v1-0-c48ec19e9ee4@gmail.com> (raw)
Use the layout-aware channel enable check during termination and retain
transfer resources when the channel does not stop. Keep suspension status
available until the polling pause path observes it, including when an
acknowledgment arrives after the polling timeout or another channel
interrupts concurrently.
