From 64d70fe5d3640e1a89790ed21120921278f8cb86 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Wed, 28 Mar 2012 07:55:56 +0200 Subject: common: DMA-mapping: add NON-CONSISTENT attribute DMA_ATTR_NON_CONSISTENT lets the platform to choose to return either consistent or non-consistent memory as it sees fit. By using this API, you are guaranteeing to the platform that you have all the correct and necessary sync points for this memory in the driver.
