When utilizing userptr buffers for output from the CCDC, the
DMA subsystem maps buffers into the virtual address space.
However, the DMA subsystem also has a configurable parameter

The OMAP3 ISP driver is moving to DT, hopefully in time for v4.1. See "[PATCH

for proper DT support instead of custom deferred probing.
