[PATCH v2] OMAP3 ISP: Set DMA segment size

2015-03-19 Thread Tim Nordell
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 for what the largest segment to allocate is out of the virtual address space as well. Since we need contiguous buffer
