From all I can tell, there are no remaining in-tree users of the driver, but it could be used by out-of-tree platform ports. I've marked the driver as 'depends on COMPILE_TEST', short of removing it outright. It was originally written for some ARM PXA machines using the same chip, but that platform never really worked and the code has been removed a long time ago.
