From mboxrd@z Thu Jan 1 00:00:00 1970 From: b38343@freescale.com (Robin Gong) Date: Wed, 10 Sep 2014 09:33:36 +0800 Subject: [PATCH v1] ARM: dts: imx6dl: disable dma support for spi on i.mx6dl Message-ID: <1410312816-32171-1-git-send-email-b38343@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
