- Subject: [PATCH] dmaengine: mediatek: add HSDMA support for mt7621
- Commit 87dd67f496f7 ("staging: mt7621-dma: remove driver from tree")
- removed the mt7621-dma driver. Move the driver from staging to the
- folder "drivers/dma/mediatek" containing already other mediatek dma
- driver implementations and maintain it downstream in OpenWrt.
- This patch will not be sent to upstream linux. It is just a workaround.
