Sadly it is not. Your patch
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
Use hwmod data and device attributes to build and register an
omap device for iommu driver.
- Update the naming convention in isp module.
- Remove unneeded check for number of resources, as this is now
handled by omap_device and prevents driver from loading.
- Now unused, remove platform

Use runtime PM functionality interfaced with hwmod enable/idle
functions, to replace direct clock operations and sysconfig
handling.
Dues to reset sequence, pm_runtime_put_sync must be used, to avoid
possible operations with the module under reset.

Save and restore context during pm runtime transitions.
For now, the previous API for this purpose will trigger
pm runtime functions, and will be left as exported symbol
for compatibility with it's only user.

These functions save and restore registers irrespectively of their
read or write permissions, this ends up in registers being saved
that can't be restored because of read only attributes. OTOH, so
far only 3 of them need to be saved.
In future GP_REG (which is present only on OMAP4 ipu) needs to
