Driver for the CIMaX SP2 common interface chip. It is very much based on the existing cimax2 driver for cx23885, but should be more reusable. The product has been sold with name Atmel T90FJR as well and the data sheets for that chip seem to be publicly available. It seems that the USB device that I have and the cx23885 based devices will need to interact differently with the chip for the CAM operations. Thus there is one callback function that is passed on to the sp2 driver (see function sp2_ci_op_cam for that one). IRQ functionality is not included currently (not needed by USB devices and I don't have a PCIe device for development).
