+Subject: usb: host: xhci: fix compilation error for non-PCI based stacks
+
+From: Moiz Sonasath <m-sonasath@ti.com>
+
+commit 296365781903226a3fb8758901eaeec09d2798e4 upstream.
+
+For non PCI-based stacks, this function call
+usb_disable_xhci_ports(to_pci_dev(hcd->self.controller));
+made from xhci_shutdown is not applicable.
+
+Ideally, we wouldn't have any PCI-specific code on
+a generic driver such as the xHCI stack, but it looks
+like we should just stub usb_disable_xhci_ports() out
+for non-PCI devices.
+
+[ balbi@ti.com: slight improvement to commit log ]
+
+This patch should be backported to kernels as old as 3.0, since the
+commit it fixes (e95829f474f0db3a4d940cae1423783edd966027 "xhci: Switch
+PPT ports to EHCI on shutdown.") was marked for stable.

+Subject: xhci: Make handover code more robust
+
+From: Matthew Garrett <mjg@redhat.com>
+
+commit e955a1cd086de4d165ae0f4c7be7289d84b63bdc upstream.
+
+My test platform (Intel DX79SI) boots reliably under BIOS, but frequently
+crashes when booting via UEFI. I finally tracked this down to the xhci
+handoff code. It seems that reads from the device occasionally just return
+0xff, resulting in xhci_find_next_cap_offset generating a value that's
+larger than the resource region. We then oops when attempting to read the
+value. Sanity checking that value lets us avoid the crash.
+
+I've no idea what's causing the underlying problem, and xhci still doesn't
+actually *work* even with this, but the machine at least boots which will
+probably make further debugging easier.
+
+This should be backported to kernels as old as 2.6.31, that contain the
+commit 66d4eadd8d067269ea8fead1a50fe87c2979a80d "USB: xhci: BIOS handoff
+and HW initialization."

+Subject: xhci: Recognize USB 3.0 devices as superspeed at powerup
+
+From: Manoj Iyer <manoj.iyer@canonical.com>
+
+commit 29d214576f936db627ff62afb9ef438eea18bcd2 upstream.
+
+On Intel Panther Point chipset USB 3.0 devices show up as
+high-speed devices on powerup, but after an s3 cycle they are
+correctly recognized as SuperSpeed. At powerup switch the port
+to xHCI so that USB 3.0 devices are correctly recognized.
