HW and chip team did simulation with tegra and PMIC and found that the boardSo the PMIC actually has a setting for the rate you're seeing but for
needs more capacitance then what Vendor recommended for proper signal
conditioning on interface. So they put the difference capactitance value and
this causes deviation in ramp delay from advertised value. In out design, we
measured the ramp time as 50mv/us when PMIC is configured for 100mV/us.
So for all settling time, we need to use the ramp as 50mV/us.
From DT, I will provide regulator-ramp-delay as 50mv/us.
But I do not have property for saying 100mv/us for PMIC configurations and
this is what makes need of 2nd property.
some resaon you can't use it?
