Subject: [PATCH v7 2/2] Documentation:add DMA support for freescale i2c driver
Date: Wed, 13 Aug 2014 17:46:55 +0800 [thread overview]
Message-ID: <1407923215-3749-3-git-send-email-yao.yuan@freescale.com> (raw)
In-Reply-To: <1407923215-3749-1-git-send-email-yao.yuan@freescale.com>
Add i2c dts node properties for eDMA support, them depend on the eDMA driver.
