Hi, The OMAP IOMMU driver is currently designed as three different pieces - a core OMAP IOMMU driver that implements the generic IOMMU API ops, a OMAP arch-specific layer that implements the OMAP specific arch iommu_functions, and an independent debugfs module. The former two are always built-in, while the last one is tristate. The driver supports OMAP2+ SoCs only, and this series performs a whole lot of cleanup and consolidates all the above pieces into a single built-in driver. The OMAP arch-specific layer is eliminated completely (absorbed into the core OMAP driver), and the debugfs portion is still maintained as a separate file, but not a separate module anymore. This cleanup and consolidation eliminates most of the currently exported functions from the OMAP IOMMU driver. The series also includes couple of fixes to the OMAP IOMMU debugfs entries - permissions on one debugfs entry, eliminate bus errors on debugfs access on disabled IOMMUs; and one enhancement to list all valid page table entries instead of listing only a page worth of data. The patches are baselined on 3.17-rc3 and on top of the OMAP IOMMU patches staged for 3.18 [1]; a reference branch with all these patches is available is hosted at [2]. I am posting this series for review with the intention to have them make it to 3.19, so I can repost once rc1 is out if needed.
