In Sink mode, on the receipt of a GotoMin message,
reduce the current consumption to some minimum level.
BUG=chrome-os-partner:33688
TEST=Manual testing
Used a Kevin, with test routine, to test GotoMin feature
on another Kevin unit.
Test routine:
if (!strcasecmp(argv[2], "gm")) {
ccprintf("send goto min\n");
send_control(port, PD_CTRL_GOTO_MIN);
send_control(port, PD_CTRL_PS_RDY);
}
Kevin with GotoMin feature:
# ectool usbpdpower 0
Port 0: SNK DRP PD 4277mV / 3000mA, max 5000mV / 3000mA / 15000mW
Port 1: Disconnected
After Test routine is executed:
# ectool usbpdpower 0
Port 0: SNK DRP PD 4906mV / 500mA, max 5000mV / 500mA / 2500mW
Port 1: Disconnected
