37cd681c02 USB: EHCI: make CONFIG_USB_EHCI_TT_NEWSCHED default to Y
This patch (as1382) changes the USB_EHCI_TT_NEWSCHED Kconfig option to
be non-experimental and to default to Y.  This option has existed for
a long time, and I have not heard any complaints concerning it.  By
contrast, several people have reported that their devices could be
made to work only by enabling the option.

The point of changing the default is to cause the option to be enabled
by distros that simply use the default settings for esoteric things
like this.

This change was motivated by Bugzilla #15649.

ba297edde4 USB: UHCI: acquire spinlock before calling start_rh()
This patch (as1392) fixes a bug in uhci-hcd: The start_rh() routine is
supposed to be called with the private spinlock held.  If an IRQ comes
in at just the wrong time, the driver will think the controller has
died when in fact it simply hasn't start yet.

The patch also addresses some issues that may prevent an URB from
being unlinked after the controller has stopped.  This is an abnormal
occurrence (ordinarily the controller stops only when the entire bus
is suspended and hence there are no active URBs), so the pathways
haven't gotten much testing.  These two changes may be a little more
than is strictly necessary, but clearly they won't hurt.

c548795abe USB: add check to detect host controller hardware removal
This patch (as1391) fixes a problem that can occur when USB host
controller hardware is hot-unplugged.  If no interrupts are generated
by the unplug then the HCD may not realize that the controller is
gone, and the subsequent unbind may hang waiting for interrupts that
never arrive.

The solution (for PCI-based controllers) is to call the HCD's
interrupt handler at the start of usb_hcd_pci_remove().  If the
hardware is gone, the handler will realize this when it tries to read
the controller's status register.

6d88e67925 USB: don't stop root-hub status polls too soon
This patch (as1390) fixes a problem that crops up when a UHCI host
controller is unbound from uhci-hcd while there are still some active
URBs.  The URBs have to be unlinked when the root hub is unregistered,
and uhci-hcd relies upon root-hub status polls as part of its
unlinking procedure.  But usb_hcd_poll_rh_status() won't make those
status calls if hcd->rh_registered is clear, and the flag is cleared
_before_ the unregistration takes place.

Since hcd->rh_registered is used for other things and needs to be
cleared early, the solution is to add a new flag (rh_pollable) and use
it instead.  It gets cleared _after_ the root hub is unregistered.

Now that the status polls don't end too soon, we have to make sure
they also don't occur too late -- after the root hub's usb_device
structure or the HCD's private structures are deallocated.  Therefore
the patch adds usb_get_device() and usb_put_device() calls to protect
the root hub structure, and it adds an extra del_timer_sync() to
prevent the root-hub timer from causing an unexpected status poll.

This additional complexity would not be needed if the HCD framework
had provided separate stop() and release() callbacks instead of just
stop().  This lack could be fixed at some future time (although it
would require changes to every host controller driver); when that
happens this patch won't be needed any more.

96e077ae34 USB: fix failure path in usb_add_hcd()
This patch (as1389) fixes some errors in the failure pathway of
usb_add_hcd().  The actions it takes ought to be exactly the same as
those taken by usb_remove_hcd(), but they aren't.

In one case (removal of the usb_bus_attr_group), the two routines are
brought into agreement by changing usb_remove_hcd().  All the other
discrepancies are fixed by changing usb_add_hcd().

c222fb2efa USB: usb-storage: fix initializations of urb fields
Commit 0ede76fcec, "USB: remove uses of
URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing
initialization of the transfer flags.  This caused initialization
failures in the ums-karma driver.  Fix the regression by zeroing it.

While at it, as Alan Stern points out, the initializers for
actual_length and status are handled by the core and error_count
only matters for isochronous urbs, so they don't need to be set here.
Remove them.

c30c791c94 USB: xhci: Set Mult field in endpoint context correctly.
The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has
different meanings, depending on the endpoint type.  If the endpoint is
isochronous, the bmAttributes field is the maximum number of packets
within a service interval that this endpoint supports.  If the endpoint is
bulk, it's the number of stream IDs this endpoint supports.

Only set the Mult field of the xHCI endpoint context using the
bmAttributes field if the endpoint is isochronous, and the device is a
SuperSpeed device.

47f19c0eed USB: adds Artisman USB dongle to list of quirky devices
When an attempt is made to read the interface strings of the Artisman
Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written
to the dmesg log (uhci_result_common: failed with status 440000) and the
dongle resets itself, resulting in a disconnect/reconnect loop.

Adding the dongle to the list of devices in quirks.c, with the same
quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D
joystick, stops the device from resetting and allows it to be used with
no problems.

2d1ee5904b USB: xhci: Set EP0 dequeue ptr after reset of configured device.
When a configured device is reset, the control endpoint's ring is reused.
If control transfers to the device were issued before the device is reset,
the dequeue pointer will be somewhere in the middle of the ring.  If the
device is then issued an address with the set address command, the xHCI
driver must provide a valid input context for control endpoint zero.

The original code would give the hardware the original input context,
which had a dequeue pointer set to the top of the ring.  This would cause
the host to re-execute any control transfers until it reached the ring's
enqueue pointer.  When issuing a set address command for a device that has
just been configured and then reset, use the control endpoint's enqueue
pointer as the hardware's dequeue pointer.

Assumption:  All control transfers will be completed or cancelled before
the set address command is issued to the device.  If there are any
outstanding control transfers, this code will not work.

809cd1cb80 USB: Fix USB3.0 Port Speed Downgrade after port reset
Without this fix, a USB 3.0 port is downgraded to full speed after a port
reset of a configured device.  The USB 3.0 terminations will be disabled
permanently, and USB 3.0 devices will always enumerate as full speed
devices, until the host controller is unplugged (if it is an ExpressCard)
or the computer is rebooted.

Fajun Chen traced this traced the speed downgrade issue to the port reset
and the interpretation of port status in USB hub driver code.  The hub
code was not testing for the port being a SuperSpeed port, and it fell
through to the else case of Full Speed.

The following patch adds SuperSpeed mapping from the port status, and
fixes the speed downgrade issue.

d1dc908a25 USB: xHCI: Fix another bug in link TRB activation change.
Commit 6c12db90f1 also seems to have
introduced a bug that is triggered when the command ring is about to wrap.
The inc_enq() function will not have moved the enqueue pointer past the
link TRB.  It is supposed to be moved past the link TRB in prepare_ring(),
which should be called before a TD is enqueued.  However, the
queue_command() function never calls the prepare_ring() function because
prepare_ring() is only supposed to be used for endpoint rings.  That means
the enqueue pointer will not be moved past the link TRB, and will get
overwritten.

The fix is to make queue_command() call prepare_ring() with a fake
endpoint status (set to running).  Then the enqueue pointer will get moved
past the link TRB.
