This looks okay to me for now - queued for 3.2.  Ideally we would move the 
Fint DPLL data to the struct dpll_data, but this would be a fairly 
significant undertaking, since we don't have a clean way to use different 
dpll_data for different OMAP3 variants.  Something good to keep in mind 
for the common clock conversion.


thanks,
