CDX bus supports the scanning and probing of FPGA based devices. These devices are registers as CDX devices. The bus driver sets up the basic infrastructure and fetches the device related information from the firmware. CDX bus is capable of scanning devices dynamically, supporting rescanning of dynamically added, removed or updated devices.
Really? Then why is the platform driver mess still in here?

Again, this should not be a platform driver. Now you can have a CDX "bus" driver, that is a platform driver, but that needs to be in a separate file and as a separate module and totally independant of the CDX bus code entirely. Otherwise this is a mess to try to sift through and determine what is, and is not, going on. Please split that up and get rid of all of the platform driver stuff here and put it in a separate patch that happens after the CDX bus logic is added. thanks, greg k-h
