Subject: [PATCH v10 0/3] Add Amlogic general DMA
Date: Fri, 10 Jul 2026 05:48:05 +0000 [thread overview]
Message-ID: <20260710-amlogic-dma-v10-0-ff4deae837e7@amlogic.com> (raw)
Add DMA driver and bindigns for the Amlogic SoCs.
Signed-off-by: Xianwei Zhao <xianwei.zhao@amlogic.com>

Changes in v10:
- Free dma memory in workqueue.
- Deal with zero len sg (not consume sg_link),and reset status to DMA_COMPLETE when terminal channel.
- Add desc for #dma-cells in dt-bindings.
- Link to v9: https://lore.kernel.org/r/20260626-amlogic-dma-v9-0-558d672c4a95@amlogic.com
Changes in v9:
- Use each transmission request sg_link mem instead of the loop mem get.
- Fix some hidden issues which reviewed by ai robot.

- When a module fails or exits, perform de-initialization.
- Some other minor modifications.
- Link to v3: https://lore.kernel.org/r/20260206-amlogic-dma-v3-0-56fb9f59ed22@amlogic.com
Changes in v3:
- Adjust the format of binding according to Frank's suggestion.
- Some code format modified according to Frank's suggestion.
