+ Most OMAPs' provide a way to specify the time for which the reset
+ should be held low while the voltages and Oscillator outputs
+ stabilize.
+ This time is mostly board and PMIC dependent. Hence the boards are
+ expected to specify a pre-computed time using the above option.
+ This value can be computed using a summation of the below 3
+ parameters
+ 1: Time taken by the Osciallator to stop and restart
+ 2: PMIC OTP time
+ 3: Voltage ramp time, which can be derived using the PMIC slew rate
+ and value of voltage ramp needed.
