2015-01-12usb: renesas_usbhs: add OTG ID signal sensingSergei Shtylyov
On the Renesas R8A7791 SoC based boards there's MAX3355 USB OTG chip and mini-AB USB connector corresponding to USB port 0 driven either by EHCI/OHCI or Renesas USBHS gadget controller. And we'd like the host/gadget drivers to work based on the cable type connected. An 'extcon' driver for MAX3355 has been written, so we only need to bind to it via device tree which I'm doing in this patch. (Perhaps, it would also make sense to use OTG HNP when the USBHS host mode is active and a B-cable is connected but I don't have access to host-capable USBHS, so wouldn't be able to test it.)

2015-01-12usb: dwc2: gadget: report disconnection after resetMian Yousaf Kaukab
If usb bus is reset without a physical disconnection, all endpoints will remain open. Call s3c_hsotg_disconnect() from reset handler to report a disconnect to gadget framework. hsotg->connected is checked in s3c_hsotg_disconnect() before processing disconnect. In some cases, USBRst is seen before EnumDone and after it as well. So move setting of hsotg->connected to set-address to avoid reporting extra disconnection in this case.

If the usb core calls disconnect notifer, the port change must happen, so it is safe to disable high speed disconenct detector, since connect notifier will be called soon if the device is still connected on the port, and we will enable high speed disconnect detector at that time.
