These patches are needed for remoteproc to work on OMAP4. Introduced iommu hwmod support for OMAP3 (iva, isp) and OMAP4 (ipu, dsp), along with the corresponding runtime PM and routines to deassert reset lines, enable/disable clocks and configure sysc registers. Due to compatibility an ifdef needs to be propagated (previously on iommu resource info) to hwmod data in OMAP3, so users of iommu and tidspbridge can avoid issues of two modules managing mmu data/irqs/resets; this until tidspbridge can be safely migrated to iommu framework. Although IOMMU hwmod patches were already submitted in the past, this series adds few more changes, like: - New reset handling, based on a series that was accepted but *NOT YET* in mainline. http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg73111.html http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg75105.html - Fix for compile break if IOMMU_API is not selected. - Save and restore context code rework. - Device tree bindings for OMAP3 and OMAP4.
