Yes, DaVinci has not migrated to common clock framework (yet). However, even without that it should be possible to use clock API in driver code. Using a callback to enable clocks or even passing the clock name from platform data would be bypassing an existing framework. Clock name should be IP specific, so it should be possible to use that in driver.

Then you'll have to create an API to expose the system module registers to drivers.

Konstantin Baydarov is working on a MFD driver for a similar module that exists in OMAP world called "control module". I guess this patch can go in though since it does not add any new accesses but merely lets the existing function be passed as NULL.
