Question about DC-DC frequency handling

[Stefan Wahren]

Hi,

i'm current working on a regulator driver which should be able to change DC-DC
clock frequency.

Now here is my question. What is the prefered way to implement the clock
handling?

Option A):

The regulator driver handles all internally (select clock source, set
frequency).

Option B):

The DC-DC clock domain is implemented in the clock driver and the regulator
driver uses the clock framework.

Best regards
Stefan
