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.

When SERIAL_8250_MT6577 is enabled, and if you want to use DMA,

you can enable the config. The DMA engine can only be used
