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. Although IOMMU hwmod patches were already submitted in the past, this series adds few more changes, like: - New reset handling. - Save and restore context code rework. - Device tree bindings for OMAP3 and OMAP4. For this series I just dropped the patches already included in mainline.
These will need to be rebased on omap-for-v3.8/cleanup-headers-iommu when I have that pushed out as that removes plat/*iommu*.h files. Regards, Tony
