Subject: [PATCH v4 2/8] iommu/rockchip: Add map_sg callback for rk_iommu_ops
Date: Tue, 21 Jun 2016 13:34:35 +0900 [thread overview]
Message-ID: <1466483681-36110-3-git-send-email-tfiga@chromium.org> (raw)
In-Reply-To: <1466483681-36110-1-git-send-email-tfiga@chromium.org>
From: Simon Xue <xxm@rock-chips.com>
The iommu_dma_alloc() in iommu/dma-iommu.c calls iommu_map_sg()
that requires the callback iommu_ops .map_sg(). Adding the
default_iommu_map_sg() to Rockchip IOMMU accordingly.
