Do you mean it is the only option to quickly get it working right now? The VC & VP code should be converted to the regulator framework if not already. After that is done there are some options for how ABB is handled. The VC & VP regulator driver could directly call the api's you list below in their .set_voltage callback. Additionally if the regulator is reentrant then ABB could be modeled as a regulator itself and the VC or VP .set_voltage callback could perhaps call regulator_set_mode(abb_reg, FBB_MODE). Creating a regulator for each ABB instance may be overkill or may not be overkill... that IP has been around since 3630 so several chips use it. > omap_abb_pre_scale(struct omap_abb *abb, u32 old_volt, u32 new_volt); > omap_abb_post_scale(struct omap_abb *abb, u32 old_volt, u32 new_volt); > > Mike, do you agree to proceed in this way?

If everything is going to get converted to the regulator framework then I do not agree to proceed that way. Let's figure out what is happening to the VC/VP code first and then figure out what to do about ABB.
