Subject: [PATCH v7 12/15] spi/s3c64xx: Add support DMA engine API
Date: Thu, 25 Aug 2011 11:13:42 +0900 [thread overview]
Message-ID: <1314238425-6480-13-git-send-email-boojin.kim@samsung.com> (raw)
In-Reply-To: <1314238425-6480-1-git-send-email-boojin.kim@samsung.com>
This patch adds to support DMA generic API to transfer raw
SPI data. Basiclly the spi driver uses DMA generic API if
architecture supports it. Otherwise, uses Samsung specific
S3C-PL330 APIs.
