The #ifdef is slightly wrong as it doesn't cover the xhci_priv_resume_quirk()
function, causing a harmless warning:
drivers/usb/host/xhci-plat.c:58:12: error: 'xhci_priv_resume_quirk' defined but not used [-Werror=unused-function]
static int xhci_priv_resume_quirk(struct usb_hcd *hcd)
A simpler way to do this correctly is to use __maybe_unused annotations
that let the compiler silently drop the functions when there is no
reference.

commit a6ff6cbf1f ("usb: xhci: Add helper function xhci_set_power_on().")
created a helper to control port power that needs to be called with
xhci->lock held and interrupts disabled.
It released the lock with spin_unlock_irqrestore using a new zero flag
variable instead of the original flag from spin_lock_irqsave.
This regression triggered a static checker warning about bogus flags, and
a null pointer dereference on armada-385.
Fix it by passing a pointer to the correct flags and using it instead

As per [1] issue #4,
"The periodic EP scheduler always tries to schedule the EPs
that have large intervals (interval equal to or greater than
128 microframes) into different microframes. So it maintains
an internal counter and increments for each large interval
EP added. When the counter is greater than 128, the scheduler
rejects the new EP. So when the hub re-enumerated 128 times,
it triggers this condition."
This results in Bandwidth error when devices with periodic
endpoints (ISO/INT) having bInterval > 7 are plugged and
unplugged several times on a TUSB73x0 XHCI host.
Workaround this issue by limiting the bInterval to 7
(i.e. interval to 6) for High-speed or faster periodic endpoints.

This patch creates a new event class called xhci_log_ring, and
defines the events used for tracing the change of all kinds of
rings used by an xhci host. An xHCI ring is basically a memory
block shared between software and hardware. By tracing changes
of rings, it makes the life easier for debugging hardware or
software problems.
This info can be used, later, to print, in a human readable way,
the life cycle of an xHCI ring using the trace-cmd tool and the
appropriate plugin.

Introduce a new xhci_hc_died() function that takes care of handling
pending commands and URBs if a host controller becomes unresponsive.
This addresses issues on hotpluggable xhci controllers that disappear
from the bus suddenly, often while the bus (PCI) remove function is
still being processed.
xhci_hc_died() sets a XHCI_STATUS_DYING flag to prevent new URBs and
commands or to be queued. The flag also ensures xhci_hc_died() will
give back pending commands and URBs once.
Host is considered dead if register read returns 0xffffffff, or host
fails to abort the command ring, or fails stopping an endpoint after
trying for 5 seconds.

USB2 test mode is a required hardware feature for system integrators
validating their hardware according to USB spec, regarding signal
strength and stuff. It is purely a hardware test feature.
Usually you need an oscilloscope and have to enable those test modes on
the hardware. This will send some specific test patterns on D+/D-. There
is no report available (in Linux itself) as it is purely externally
visible. Regular USB usage is not possible at that time.
Anyone (well access to e.g. /dev/bus/usb/001/001 provided) can use it by
sending appropriate USB_PORT_FEAT_TEST requests to the hub.

EINT(Event Interrupt) is a write-1-to-clear type of bit in xhci
status register. It should be cleared by writing a 1. Writing 0
to this bit has no effect.
Xhci driver tries to clear this bit by writing 0 to it. This is
not the right way to go. This patch corrects this by reading the
register first, then clearing all RO/RW1C/RsvZ bits and setting
the clearing bit, and writing back the new value at last.
Xhci spec requires that software that uses EINT shall clear it
prior to clearing any IP flags in section 5.4.2. This is the
reason why this patch is CC'ed stable as well.

2 We fail to find xhci internal structures from urb private data such as
virtual device and endpoint ring.

3 URB private data has valid pointers to xhci internal data, but host is
not responding.
give back URB immedately and remove the URB from the endpoint lists.
4 Everyting is working
add URB to cancel list, queue a command to stop the endpoint, after
which the URB can be turned to no-op or skipped, removed from lists,
and given back.
We failed to give back the urb in case 2 where the correct device and
endpoint pointers could not be retrieved from URB private data.
This caused a hang on Dell Inspiron 5558/0VNM2T at resume from suspend
as urb was never returned.

On a loaded virtualization host (dozen guests booting at the same time)
it may happen that the ohci controller emulation doesn't manage to do
timely frame processing, with the result that the io watchdog fires and
considers the controller being dead, even though it's only the emulation
being unusual slow due to the load peak.
So, add a quirk for qemu and don't use the watchdog in case we figure we
are running on emulated ohci. The virtual ohci controller masquerades
as apple ohci controller, but we can identify it by subsystem id.
