- * usb_hcd_suspend_root_hub - HCD autosuspends downstream ports

- *
- * This call arranges that usb_hcd_resume_root_hub() is safe to call later;
- * that the HCD's root hub polling is deactivated; and that the root's hub
- * driver is suspended. HCDs may call this to autosuspend when their root
- * hub's downstream ports are all inactive: unpowered, disconnected,
- * disabled, or suspended.
- *
- * The HCD will autoresume on device connect change detection (using SRP
- * or a D+/D- pullup). The HCD also autoresumes on remote wakeup signaling
- * from any ports that are suspended (if that is enabled). In most cases,
- * overcurrent signaling (on powered ports) will also start autoresume.
- *
- * Always called with IRQs blocked.
