Merge ohci_finish_controller_resume with ohci_resume as suggested by Alan
Stern. Since ohci_finish_controller_resume no longer exists, update the
various OHCI drivers to call ohci_resume() instead. Some drivers used to set
themselves the bit HCD_FLAG_HW_ACCESSIBLE, which is now handled by
ohci_resume().

As suggested by Alan Stern, move the ohci-pci.c ohci_pci_{suspend,resume}
routines to ohci-hcd.c. Due to their move, also rename them to
ohci_{suspend,resume} to make it clear they operate on ohci_hcd. Since they
are not necessarily called, annotate them with __maybe_unused, and make them
enclosed within an #ifdef CONFIG_PM / #endif section.

Enhance the ehci-platform driver to also accept no_io_watchdog as a platform
data parameter. When no_io_watchdog is set to 1, the ehci controller will set
ehci->need_io_watchdog to 0. Since most EHCI controllers do need the I/O
watchdog to be on, only let those which need it to turn the watchdog off.

Make sure that we change need_io_watchdog after the call to ehci_setup()
because ehci_setup() will unconditionnaly set need_io_watchdog to 1.

Alan Stern 6a41b4d3fe OHCI: implement new semantics for URB_ISO_ASAP
This patch (as1614) updates the isochronous scheduling in ohci-hcd to
match the new semantics for URB_ISO_ASAP.  Testing revealed a hardware
bug in the way my OHCI controller handles expired isochronous TDs;
consequently the patch tries hard to avoid creating them (unlike the
ehci-hcd and uhci-hcd drivers).

Alan Stern 98cae42d82 EHCI: use the isochronous scheduling threshold
This patch (as1609) changes the way ehci-hcd uses the "Isochronous
Scheduling Threshold" in its calculations.  Until now the code has
ignored the threshold except for certain Intel PCI-based controllers.
This violates the EHCI spec.

The new code takes the threshold into account always, removing the
need for the fs_i_thresh quirk flag.  In addition it implements the
"full frame cache" setting more efficiently, moving forward only as
far as the next frame boundary instead of always moving forward 8
microframes.

Alan Stern c3ee9b76aa EHCI: improved logic for isochronous scheduling
This patch (as1608) reworks the logic used by ehci-hcd for scheduling
isochronous transfers.  Now the modular calculations are all based on
a window that starts at the last frame scanned for isochronous
completions.  No transfer descriptors for any earlier frames can
possibly remain on the schedule, so there can be no confusion from
schedule wrap-around.  This removes the need for a "slop" region of
arbitrary size.

There's no need to check for URBs that are longer than the schedule
length.  With the old code they could throw things off by wrapping
around and appearing to end in the near future rather than the distant
future.  Now such confusion isn't possible, and the existing test for
submissions that extend too far into the future will also catch those
that exceed the schedule length.  (But there still has to be an
initial test to handle the case where the schedule already extends as
far into the future as possible.)

Delays caused by IRQ latency won't confuse the algorithm unless they
are ridiculously long (over 250 ms); they will merely reduce how far
into the future new transfers can be scheduled.  A few people have
reported problems caused by delays of 50 ms or so.  Now instead of
failing completely, isochronous transfers will experience a brief
glitch and then continue normally.

(Whether this is truly a good thing is debatable.  A latency as large
as 50 ms generally indicates a bug is present, and complete failure of
audio or video transfers draws people's attention pretty vividly.
Making the transfers more robust also makes it easier for such bugs to
remain undetected.)

Finally, ehci->next_frame is renamed to ehci->last_iso_frame, because
that better describes what it is: the last frame to have been scanned
for isochronous completions.

Greg Kroah-Hartman 6b7ced68f3 usb: fixes for v3.7-rc2
Here's the first set of fixes for v3.7-rc cycle.
 
 DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
 standing bug which would keep endpoint with BUSY flag set forever if we cancel
 a transfer which has already been started by the controller. The second fix
 will just switch PHYs back off when DWC3 driver is removed.
 
 MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
 removing a device. For some reason that particular device can fall into a
 situation where you have both Disconnect and Endpoint IRQs happen
 simultaneously (have both bits set in IRQ_STATUS register) and, because
 Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
 transfer data over a disconnected device, thus generating a kernel oops.
 
 Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
 the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
 in order to properly clear a single Interrupt event without clearing (and
 masking) other events we didn't handle yet.

usb: fixes for v3.7-rc2

Here's the first set of fixes for v3.7-rc cycle.

DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
standing bug which would keep endpoint with BUSY flag set forever if we cancel
a transfer which has already been started by the controller. The second fix
will just switch PHYs back off when DWC3 driver is removed.

MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.

Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.

Alan Stern db5c8b5244 USB: fix port probing and removal in garmin_gps
This patch (as1615) fixes a bug in the Garmin USB serial driver.  It
uses attach, disconnect, and release routines to carry out actions
that should be handled by port_probe and port_remove routines, because
they access port-specific data.

The bug causes an oops when the device in unplugged, because the
private data for each port structure now gets erased when the port is
unbound from the driver, resulting in a null-pointer dereference.

Fix port-data memory leak by allocating and freeing port data in

serial private data to store the device type which is interface rather

Since commit 0998d06310 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer freed at release.
