Subject: [PATCH 12/14] common: dma-mapping: introduce mmap method
Date: Fri, 23 Dec 2011 13:27:31 +0100 [thread overview]
Message-ID: <1324643253-3024-13-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1324643253-3024-1-git-send-email-m.szyprowski@samsung.com>
Introduce new generic mmap method with attributes argument.
This method lets drivers to create a userspace mapping for a DMA buffer
in generic, architecture independent way.
