Subject: [PATCH 10/29] drivers: add DRIVER_HAS_OWN_IOMMU_MANAGER flag
Date: Tue, 05 Aug 2014 12:47:38 +0200 [thread overview]
Message-ID: <1407235677-26324-11-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1407235677-26324-1-git-send-email-m.szyprowski@samsung.com>
This patch adds a new flags for device drivers. This flag instructs
kernel that the device driver does it own management of IOMMU assisted
IO address space translations, so no default dma-mapping structures
should be initialized.
