You need to check the omap package type you're using to find
out the correct ball name. If you get lucky, that's already in
mux34xx.c and you don't need search through the TRMs :)

Then you want to use the full signal name:

omap_mux_init_signal("mode0_name.desired_mode", OMAP_PIN_FLAGS) 

But as the balls can be separate for each package type, you
need to figure that out first.
