+       help
+         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.
