I can reproduce this issue using top of head U-boot tree.

It seems indeed to be caused by:

    pmic: Extend PMIC framework to support multiple instances of PMIC devices

    The PMIC framework has been extended to support multiple instances of
    the variety of devices responsible for power management.
    This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB
    Interface Circuit).
    Power related includes have been moved to ./include/power directory.
    This is a first of a series of patches - in the future "pmic" will be
    replaced with "power".

    Two important issues:
    1. The PMIC needs to be initialized just after malloc is configured
    2. It uses list to hold information about available PMIC devices

I am Ccing Lukasz/Stefano in case they have any suggestion.

With the new PMIC framework: is it safe to call the PMIC API from
board_init function?
