Subject: [PATCH 0/6+1] ARM: EXYNOS4: SYSMMU: Improvements on SYSMMU driver
Date: Mon, 4 Jul 2011 10:41:41 +0900 [thread overview]
Message-ID: <1309743708-1505-1-git-send-email-pullip.cho@samsung.com> (raw)
This patch set includes the following patches:
- [PATCH 1/6] ARM: EXYNOS4: SYSMMU: Remove SYSMMU_MDMA2
The previous driver defines System MMUs for 2 MDMAs each.
Since one of the MDMAs is not used any more, it is removed.
SYSMMU_MDMA2 is renamed to SYSMMU_MDMA and it now represents number 10.
- [PATCH 2/6] ARM: EXYNOS4: SYSMMU: Enable clock gating for System MMUof SSS
System MMU of SSS was not complete to use because previous driver did not
prepare anything for its clock gating feature. This patch enables clock
gating for System MMU of SSS.
- [PATCH 3/6] ARM: EXYNOS4: SYSMMU: Enhancement on device definition
As the suggestion of Marek Szyprowski with his patch set, this patch
separates the single definition of platform device of System MMU into
15 different platform devices as well as structured resource management.
- [PATCH 4/6] ARM: EXYNOS4: SYSMMU: add devname in SYSMMU clock to support clkdev.
This patch adds 'devname' fields into the clokc definitions of System MMU.
The pointer to clk structure for System MMU can be found with kobj name
dynamically.
- [PATCH 5/6] ARM: EXYNOS4: SYSMMU: Add SYSMMU_NONE
This patch adds another System MMU ID(ips), "SYSMMU_NONE" which means
invalid system MMU ID.
- [PATCH 6/6] ARM: EXYNOS4: SYSMMU: Move clock gating functions to SYSMMU device driver.
The previous driver implements clock gating functions in the mach
directory because it is mach dependent. It is now removed and
clock gating functions are moved to System MMU driver because clkdev is
supported.
- [PATCH] ARM: EXYNOS4: iommu: Add IOMMU API and moved to drivers/iommu
This patch moves the existing System MMU driver to drivers/iommu
directory that is in Joerg Roedel's git.
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git
This patch also adds implementation of IOMMU API for Exynos4's System MMU.
The above patches must be applied in the order of their presence.
The last patch is not applicable to any kernel version except Joerg
Roedel's git tree.
This patch set does not improve System MMU driver completely.
The rest of enhancements will be submitted soon.
Regards,
KyongHo Cho.
