[PATCH v4 1/3] usb: notify hcd when USB device suspend or resume

2015-05-08 Thread Lu Baolu
This patch adds two new entries in hc_driver. With these new entries, USB core can notify host driver when a USB device is about to suspend or just resumed. The xHCI spec is designed to allow an xHC implementation to cache the endpoint state. Caching endpoint state allows an xHC to reduce latency
