I looked for last 4 communication and tried to find out if any typo on 
mail so that I can correct but did not found.

/**
Here is the case,
PMIC supports 2 ramp time configurations 5mv/us and 100mV/us. This is 
supported with some specific capacitance in rail output per 
recommendation from PMIC
**/

So may be more older may have..

But here is the stuff without typo ;-)
Device supports 5mV/us and 100mV/us which is not in observed value.

And this is the only reason for requesting of second property.
