Detailed Description

Linear Technology DC1962C Demonstration Board LTC3880, LTC2974, LTC2977: Power Management Solution for Application Processors.

Demonstrates SVID using PMBus and LTC3880 for QorIQ. The SVID values
are 0, 1, 2, 3. 3 is treated as VBOOT. When run, the script sets VBOOT
and then the voltage can be lowered in 12.5mV steps by selecting a number.

NOTES
  Setup:
   Set the terminal baud rate to 115200 and select the newline terminator.
