-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.
