2012-12-03iommu/omap: Adapt to runtime pmOmar Ramirez Luna
Use runtime PM functionality interfaced with hwmod enable/idle functions, to replace direct clock operations and sysconfig handling. Due to reset sequence, pm_runtime_[get|put]_sync must be used, to avoid possible operations with the module under reset. Because of this and given that the driver uses spin_locks to protect their critical sections, we must use pm_runtime_irq_safe in order for the runtime ops to be happy, otherwise might_sleep_if checks in runtime framework will complain. The remaining pm_runtime out of iommu_enable and iommu_disable corresponds to paths that can be accessed through debugfs, some of them doesn't work if the module is not enabled first, but in future if the mmu is idled withouth freeing, these are needed to debug.

Move some of the definitions in omap-iommu.h that can be made local to either drivers/iommu.

2012-11-20ARM: OMAP2+: Move iommu2 to drivers/iommu/omap-iommu2.cTony Lindgren
This file should not be in arch/arm. Move it to drivers/iommu to allow making most of the header local to drivers/iommu. This is needed as we are removing plat and mach includes from drivers for ARM common zImage support.
