It looks better because the driver is already including related
headers in a similar fashion, but in reality those headers are under
arch/arm/mach-omap2 and the driver shouldn't have any business in
including headers from there.

Ok, not a problem, I'll be working on the real fix which is to get
APIs from the core code for the driver to use.
