2014-05-30	iommu/msm: Use devm_ioremap_resource to simplify code	Kefeng Wang	1	-31/+7
	Use devm_ioremap_resource() to make the code simpler, drop unused variable, redundant return value check, and error-handing code. Signed-off-by: Kefeng Wang <wangkefeng.wang@huawei.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2013-09-11	drivers/iommu: remove unnecessary platform_set_drvdata()	Jingoo Han	1	-2/+0
	The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

2013-08-06	iommu/msm: Move mach includes to iommu directory	Stephen Boyd	1	-2/+2
	Two header files exist in mach-msm's include/mach directory that are only used by the MSM iommu driver. Move these files to the iommu driver directory and prefix them with "msm_". This allows us to compile the MSM iommu driver on multi-platform kernels.

2013-07-09	drivers/iommu/msm_iommu_dev.c: fix leak and clean up error paths	Libo Chen	1	-14/+10
	Fix two obvious problems: 1. We have registered msm_iommu_driver first, and need unregister it when registered msm_iommu_ctx_driver fail 2. We don't need to kfree drvdata before kzalloc was successful.

2013-06-24	msm: iommu: Use clk_set_rate() instead of clk_set_min_rate()	Stephen Boyd	1	-2/+1
	Calling clk_set_min_rate() is no better than just calling clk_set_rate() because MSM clock code already takes care of calling the min_rate ops if the clock really needs clk_set_min_rate() called on it.

2013-06-24	msm: iommu: Convert to clk_prepare/unprepare	Stephen Boyd	1	-7/+10
	Add calls to clk_prepare and unprepare so that MSM can migrate to the common clock framework. We never unprepare the clocks until driver remove because the clocks are enabled and disabled in irq context. Finer grained power management is possible in the future via runtime power management techniques.

2011-06-21	msm: iommu: move to drivers/iommu/	Ohad Ben-Cohen	1	-0/+422
	This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Compile-tested for MSM8X60.
