README on how reset time on OMAPs should be calculated
CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC:
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, (the details on how to compute
the value are given below) without which a default time
as specified by CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC
is used.
The value for CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC
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.
