Any reason for switching the name to mmu_isp?
The name of the hwmod is "mmu_isp". This was not working otherwise,
but I cannot tell you for sure why without getting back at my office.
Ok, did a bit of digging, this is due to the name tie-in for iommu arch
data (look at the omap3_camera_init in mach-omap2/devices.c), and the
obj->name assignment of of->name. This is another thing that needs to be
looked into since it would be preferable to move away from the name
based lookup towards using a phandle approach by the iommu consumer drivers.
