For kevin, we are not using the PROCHOT# signal for the charger so we can enable a power save mode. This commit will leave BGATE on but without monitoring the PROCHOT# signal. When VBUS or VCC is removed from the charger, the charger will enter this power save mode. It will return to normal functionality when VBUS or VCC is applied. BUG=chrome-os-partner:55631 BRANCH=kevin TEST=Flash kevin; Verify we can still charge; Verify that power consumption is less with this patch applied than without.
