    SubjectNVMEM usage question
    From
    Date
    Hi,

    Mediatek PMIC chip have some spare registers used to store information.
    The value of these registers will exist until user unplug battery or
    battery depletion. One of our usage example is store battery utilization
    in these spare registers. We want to implement NVMEM driver to
    read/write sparse registers, but binding document describe NVMEM is for
    "Non-volatile memory", and for hardware like eeprom, efuse. Since the
    usage here is some kind of "battery backup memory", but not real
    non-volatile memory, is NVMEM driver suitable for this case ?

    Eddie
