The CCP driver generally uses a round-robin approach when assigning operations to available CCPs. For the DMA engine, however, the DMA mappings of the SGs are associated with a specific CCP. When an IOMMU is enabled, the IOMMU is programmed based on this specific device. If the DMA operations are not performed by that specific CCP then addressing errors and I/O page faults will occur. Update the CCP driver to allow a specific CCP device to be requested for an operation and use this in the DMA engine support.
