I am going to introduce this update in patch 4 of this series when the 
LM36274 is introduced to the regulator driver.

It makes more sense to add it there as in patch 1 there is not really a 
need to extend the value or mask as it only supports the LM3632 device.  
It makes sense to add the condition when adding another device to support

Thoughts?
