Ok sounds good. If so, I could go ahead and change the units in the
bq2425x_charger.c over to mA and mV? It would be a bit labor some and I
also want to see what Laurentiu thinks but this way we could have most
of those TI charger drivers use the same units (the new bq24261 driver
Ram posted also uses mA/mV). Except bq25890_charger.c.... that would
still use uA/uV....

Laurentiu -- what made you chose the "micro" units for bq24257_charger.c
and bq25890_charger.c?

Thanks,
