[PATCH v1] ARM: dts: imx6dl: disable dma support for spi on i.mx6dl

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




There is one weird data in rxfifo after one full rx/tx transfer
done sometimes. It looks a design issue and hard to workaround
totally, so disable dma functhion here. And will re-enable it
once the root cause found.
