Subject: [PATCH v1] ARM: dts: imx6dl: disable dma support for spi on i.mx6dl
Date: Wed, 10 Sep 2014 09:33:36 +0800 [thread overview]
Message-ID: <1410312816-32171-1-git-send-email-b38343@freescale.com> (raw)
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.
