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 ?
