[PATCH 0/5] Voltage monitor on ZII's VF610 boards

From: Andrey Smirnov <hidden>
Date: 2020-01-14 15:19:26

Everyone:

This series configures voltage supply rail monitoring on all
applicable ZII VF610 boards. Should be pretty straightforward, but let
me know if any changes are necessary.

Thanks,
Andrey Smirnov
