As per Bjorn's comment I have removed the default values.
Do you want to add them back ?

Same as above.

"ovp" is already being used in pm8941-wled.c driver. That's why I am 
using ovp-millivolt.
If I rename this, i think I have to rename the existing "qcom,ovp" also, 
which will break
the backward compatibility.
