Ignore battery readings over 100%. This fixes a samus bug
where a false battery SOC reading causes charging to
stop.
BUG=chrome-os-partner:36115, chrome-os-partner:36081
BRANCH=samus
TEST=add following code to common/smart.c:
static int reset_soc;
in battery_get_params():
if (reset_soc) {
batt_new.state_of_charge = 65535;
reset_soc = 0;
}
after battery_get_params():
static int command_battsoc(int argc, char **argv)
{
reset_soc = 1;
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND(battsoc, command_battsoc,
"",
"",
NULL);
This changes the battery state of charge to 65535% for one
loop through charge state machine. w/o this CL, on samus the
battery stops charging when you call this, but with this CL
it is fixed.
