+Subject: usb: dwc3: core: fix order of PM runtime calls
+
+From: Felipe Balbi <balbi@ti.com>
+
+commit fed33afce0eda44a46ae24d93aec1b5198c0bac4 upstream.
+
+Currently, we disable pm_runtime before all register
+accesses are done, this is dangerous and might lead
+to abort exceptions due to the driver trying to access
+a register which is clocked by a clock which was long
+gated.
+
+Fix that by moving pm_runtime_put_sync() and pm_runtime_disable()
+as the last thing we do before returning from our ->remove()
+method.

+Subject: usb: dwc3: core: fix ordering for PHY suspend
+
+From: Felipe Balbi <balbi@ti.com>
+
+commit dc99f16f076559235c92d3eb66d03d1310faea08 upstream.
+
+We can't suspend the PHYs before dwc3_core_exit_mode()
+has been called, that's because the host and/or device
+sides might still need to communicate with the far end
+link partner.

+Subject: usb: host: xhci: fix compliance mode workaround
+
+From: Felipe Balbi <balbi@ti.com>
+
+commit 96908589a8b2584b1185f834d365f5cc360e8226 upstream.
+
+Commit 71c731a (usb: host: xhci: Fix Compliance Mode
+on SN65LVP3502CP Hardware) implemented a workaround
+for a known issue with Texas Instruments' USB 3.0
+redriver IC but it left a condition where any xHCI
+host would be taken out of reset if port was placed
+in compliance mode and there was no device connected
+to the port.
+
+That condition would trigger a fake connection to a
+non-existent device so that usbcore would trigger a
+warm reset of the port, thus taking the link out of
+reset.
+
+This has the side-effect of preventing any xHCI host
+connected to a Linux machine from starting and running
+the USB 3.0 Electrical Compliance Suite because the
+port will mysteriously taken out of compliance mode
+and, thus, xHCI won't step through the necessary
+compliance patterns for link validation.
+
+This patch fixes the issue by just adding a missing
+check for XHCI_COMP_MODE_QUIRK inside
+xhci_hub_report_usb3_link_state() when PORT_CAS isn't
+set.
+
+This patch should be backported to all kernels containing
+commit 71c731a.
