What is "it" and why can't we check what the current configuration is
while setting FPS to NONE?

I will have platform specific data in callback of enable/disable only.
Which call back do I need to set this? enable/disable or post register?

I'm sorry but I can't parse what you're saying here.

Here, before machine constraint applies, I need to configure FPS on desired
source.

I'm a bit confused here - I had thought you needed things the other way
around?  Can you describe in concrete terms what you want to configure?

I need to set the FPS src properly for each rails before callback happen
from regulator init so that enable/disable/is_enable can handle it properly.

Why not just reorder the callback so it happens before the constraints
are applied?

which callback I need to reorder for getting the context for configruation?

The existing call to parse the DT.

Are we allow to do i2c transfer in the existing callback for parsing the DT?

Yes, of course.
