# Detect the usb type-a port add/remove event and use the ectool
# to inform ec to enable/disable the charging in suspend mode.
# If the type-a port isn't used before the system enters suspend,
# we can turn the usb charging off after the system enters suspend.
# Once the system resume, the usb charging will be turned on by default.
# This feature can reduce the power consumption of suspend mode by
# turning off the type-a redriver.
