Cover letter [PATCH v2 0/7] omap: iommu migration, relocation and cleanups
Quoted 8 lines · Ohad Ben-Cohen

Ohad Ben-Cohen (7):
omap: iommu: migrate to the generic IOMMU API
omap: iommu/iovmm: move to dedicated iommu folder
omap: iommu: stop exporting local functions
omap: iommu: PREFETCH_IOTLB cleanup
omap: iovmm: remove unused functionality
omap: iommu: remove unused exported API
omap: iommu: omapify 'struct iommu' and exposed API

Applied all to arm/omap, thanks Ohad. I also put a commit on-top which finished the mutex->spin_lock conversion. Looks like one call-place was missed. See attached patch.

omap: iommu: Fix up mutex->spin_lock conversion of iommu_lock

The omap_iommu_set_isr() was still using the mutex functions but the iommu_lock was converted to a spin_lock. Fix that up.
