sasuke : set charging current/voltage
Charging Voltage (Battery → Charger IC)
Need 100mV margin between battery allowable voltage
and Charger IC set voltage.
8860mV → 8760mV
8400mV → 8300mV
Charger Current
Need 10% marging between battery allowable current
and Charging current.
- Normal temperature (Battery → Charger IC)
~8.24V : 6916mA → 6224mA
~8.44V : 5320mA → 4788mA
~8.86V : 4256mA → 3830mA
BUG=b:178565802
BRANCH=None
TEST=make -j BOARD=sasuke
