ipu.h is used by the dmaengine and IRQ driver under drivers/dma/ipu/, and 
by its users drivers/media/platform/soc_camera/mx3_camera.c and 
drivers/video/mx3fb.c. It has been placed under arch/arm/... because it's 
arch-specific, but in principle I don't see any reason why it cannot 
happily live anywhere under include/...
