samus: make sure EC sends battery percentage to PD on change
Make sure the EC sends the battery state of charge to the PD every
time it changes.
BUG=none
BRANCH=samus
TEST=create command to fake battery percentage in
driver/battery/smart.c:
static int cmd_battfake(int argc, char **argv)
{
char *e;
if (argc > 1)
batt_fake = strtoi(argv[1], &e, 0);
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND(battfake, cmd_battfake, NULL, "", NULL);
and in battery_get_params():
if (batt_cap > -1)
batt_new.remaining_capacity = batt_cap;
On samus use battfake command to change battery percentage back and
forth every few seconds for minutes and make sure the PD receives
host command 0x100 and that it is still happy.
