Subject: [PATCH v2 0/5] dma: don't set chancnt
Date: Sat, 15 Apr 2023 17:55:12 +0800 [thread overview]
Message-ID: <20230415095517.2763-1-jszhang@kernel.org> (raw)
I'm patching dw-axi-dmac to add more features, but I found a small
clean up point and some drivers in drivers/dma/ have the same issue,
so this series comes.
The dma framework will calculate the dma channels chancnt, setting it
is wrong.
NOTE: I leave drivers/dma/ioat/ as is, because its logic have a
heavy dependency on chancnt usage, however it's still doable.
Since v1:
- collet Acked-by tag
- fix typo

dmaengine: dw-axi-dmac: Don't set chancnt
dmaengine: axi-dmac: Don't set chancnt
dmaengine: plx_dma: Don't set chancnt
dmaengine: hidma: Don't set chancnt
dmaengine: sprd: Don't set chancnt
