| # 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. |
