dma_mask and coherent_dma_mask can be specified during 
device creation.  See usb_musb_init() in arch/arm/mach-omap2/usb-musb.c 
for an example.
Thanks for pointing this out. Should omap_device_build() start handling this
or would that be an overkill?
If both dma_mask and coherent_dma_mask are always 0xffffffff on all OMAPs 
and we can set that safely even for devices that don't use it, then yeah 
it sounds like we should set it.
I guess that's the case here also.
 
Care to send a patch?
Sure. Let me check with Mugunthan once.
