Subject: [PATCH 0/4] iommu/exynos: Add IOMMU and Enhance System MMU for Exynos4
Date: Sat, 24 Sep 2011 09:38:42 +0900 [thread overview]
Message-ID: <1316824726-20695-1-git-send-email-pullip.cho@samsung.com> (raw)
Hi,
The first 2 patches are the revolutionary change to the device definition
of System MMU for Exynos4 SoCs:
- System MMU ID is removed and a device and its dedicated System MMU are
bound during the machine initialization.
- Only the System MMU platform devices that are bound to their master
devices are initialized. If a System MMU is not initialized, it is no
longer available.
- Clock gating of System MMU with clkdev.
- Moved System MMU driver to the IOMMU's dedicated directory,
drivers/iommu.
The last 2 patches introduce new IOMMU API implementation for Exynos4
System MMU. They implements all IOMMU API including Ohad's latest
suggestion about MMU fault handling and Joerg's suggestion about
bus_type.
