That's a dependency on MACH_OMAP instead of ARM though, which is a bit
different.
(Getting offtopic and) speaking of this one, is anyone working
on converting the last four or five drivers to the dmaengine framework?
drivers/media/platform/omap/omap_vout_vrfb.c
drivers/mtd/onenand/omap2.c
drivers/usb/gadget/udc/omap_udc.c
drivers/usb/musb/tusb6010_omap.c
(and a bit of drivers/video/fbdev/omap/omapfb_main.c)
I guess we could improve build coverage by moving
arch/arm/plat-omap/dma.c into drivers/dma/omap-dma.c, but that
has the disadvantage of exposing a nonstandard interface from
somewhere inside of the dmaengine subsystem.
