[PATCH v2 0/9] OMAP: iommu: hwmod, reset handling and runtime PM

From: Omar Ramirez Luna
Date: Wed Sep 12 2012 - 15:45:52 EST

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.


- Fix for compile break if IOMMU_API is not selected.
- Save and restore context code rework.
- Device tree bindings for OMAP3 and OMAP4.
