2016-11-14xhci: rename endpoint related trb variablesMathias Nyman
Renaming variables, no functional changes Event trbs on the event ring cointain a pointer to the transfer trb on a endpoint ring that caused the event. The naming has been very confusing as the event trb was called "event" and the endpoint transfer trb was called "event_trb". rename all variables that are realated to the endpoint transfer trb from event_* to ep_* No functional changes Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-11-14xhci: remove extra URB_SHORT_NOT_OK checks in xhci, core handles most casesMathias Nyman
We only check for the URB_SHORT_NOT_OK urb flag to set the urb status to -EREMOTEIO for transfers that didn't transfer all data. This will be done in __usb_hcd_giveback() for other than isoc tranfers, so remove the redundant check from xhci. Also fix a couple split lines in debug messages to make them greppable.

The UHCI controllers in Intel chipsets rely on a platform-specific non-PME mechanism for wakeup signalling. They can generate wakeup signals even though they don't support PME.

2016-10-20xhci: workaround for hosts missing CAS bitMathias Nyman
If a device is unplugged and replugged during Sx system suspend some Intel xHC hosts will overwrite the CAS (Cold attach status) flag and no device connection is noticed in resume. A device in this state can be identified in resume if its link state is in polling or compliance mode, and the current connect status is 0. A device in this state needs to be warm reset. Intel 100/c230 series PCH specification update Doc #332692-006 Errata #8 Observed on Cherryview and Apollolake as they go into compliance mode if LFPS times out during polling, and re-plugged devices are not discovered at resume.

2016-09-08xhci: fix null pointer dereference in stop command timeout functionMathias Nyman
The stop endpoint command has its own 5 second timeout timer. If the timeout function is triggered between USB3 and USB2 host removal it will try to call usb_hc_died(xhci_to_hcd(xhci)->primary_hcd) the ->primary_hcd will be set to NULL at USB3 hcd removal. Fix this by first checking if the PCI host is being removed, and also by using only xhci_to_hcd() as it will always return the primary hcd.

2016-08-30usb: ohci-at91: Forcibly suspend ports while USB suspendWenyou Yang
The usb controller does not manage correctly the suspend mode for the ehci. In echi mode, there is no way to suspend without any device connected to it. This is why this specific control is added to fix this issue. Since the suspend mode works in ohci mode, this specific control works by suspend the usb controller in ohci mode. This specific control is by setting the SUSPEND_A/B/C fields of SFR_OHCIICR(OHCI Interrupt Configuration Register) in the SFR while the OHCI USB suspend. This set operation must be done before the USB clock disabled, clear operation after the USB clock enabled.
