H Hartley Sweeten af3f233fd2 usb: ohci-ep93xx: tidy up driver (*probe) and (*remove)
Merge the usb_hcd_ep93xx_probe() into ohci_hcd_ep93xx_drv_probe() and
the usb_hcd_ep93xx_remove() into ohci_hcd_ep93xx_drv_remove(). As Alan
Stern pointed out, there is no reason for them to be separate.

Also, as Alan Stern suggested, eliminate the ep93xx_start_hc() and
ep93xx_stop_hc() routines and simply call clk_enable() and clk_disable()
directly. The extra level of redirection does not add any clarity.

Chen Wang 140983c283 USB: usb-skeleton.c: add retry for nonblocking read
Updated skel_read() in usb-skeleton.c. When there is no data in the
buffer, we would allow retry for both blocking and nonblocking cases.
Original logic give retry only for blocking case. Actually we can also
allow retry for nonblocking case. This will reuse the existing retry
logic and handle the return of -EAGAIN in one place. Also if the data to
be read is short and can be retrieved in quick time, we can also give a
chance for nonblocking case and may catch the data and copy it back to
userspace in one read() call too.

Hans de Goede 5dc50c357d usbfs: Allow printer class 'get_device_id' without needing to claim the intf
For certain (HP) printers the printer device_id does not only contain a
static part identifying the printer, but it also contains a dynamic part
giving printer status, ink level, etc.

To get to this info various userspace utilities need to be able to make a
printer class 'get_device_id' request without first claiming the interface
(as that is in use for the actual printer driver).

Since the printer class 'get_device_id' request does not change interface
settings in anyway, allowing this without claiming the interface should not
cause any issues.

George Cherian 07f3cb7c28 usb: host: xhci: Enable XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0
Xhci controllers with hci_version > 0.96 gives spurious success
events on short packet completion. During webcam capture the
"ERROR Transfer event TRB DMA ptr not part of current TD" was observed.
The same application works fine with synopsis controllers hci_version 0.96.
The same issue is seen with Intel Pantherpoint xhci controller. So enabling
this quirk in xhci_gen_setup if controller verion is greater than 0.96.
For xhci-pci move the quirk to much generic place xhci_gen_setup.

Note from Sarah:

The xHCI 1.0 spec changed how hardware handles short packets.  The HW
will notify SW of the TRB where the short packet occurred, and it will
also give a successful status for the last TRB in a TD (the one with the
IOC flag set).  On the second successful status, that warning will be
triggered in the driver.

Software is now supposed to not assume the TD is not completed until it
gets that last successful status.  That means we have a slight race
condition, although it should have little practical impact.  This patch
papers over that issue.

It's on my long-term to-do list to fix this race condition, but it is a
much more involved patch that will probably be too big for stable.  This
patch is needed for stable to avoid serious log spam.

This patch should be backported to kernels as old as 3.0, that
contain the commit ad808333d8 "Intel xhci:
Ignore spurious successful event."

The patch will have to be modified for kernels older than 3.2, since
that kernel added the xhci_gen_setup function for xhci platform devices.
The correct conflict resolution for kernels older than 3.2 is to set
XHCI_SPURIOUS_SUCCESS in xhci_pci_quirks for all xHCI 1.0 hosts.

drivers/usb/host/xhci.c:3901:12: warning: 'xhci_change_max_exit_latency' defined but not used [-Wunused-function]

These functions are not always used, and since they're marked static
they will produce build warnings:
- xhci_msix_sync_irqs is only used with CONFIG_PCI.
- xhci_change_max_exit_latency is a little more complicated with
  dependencies on CONFIG_PM and CONFIG_PM_RUNTIME.

Instead of building a bigger maze of ifdefs in this code, I've just
marked both with __maybe_unused.

Sarah Sharp 203a86613f xhci: Avoid NULL pointer deref when host dies.
When the host controller fails to respond to an Enable Slot command, and
the host fails to respond to the register write to abort the command
ring, the xHCI driver will assume the host is dead, and call
usb_hc_died().

The USB device's slot_id is still set to zero, and the pointer stored at
xhci->devs[0] will always be NULL.  The call to xhci_check_args in
xhci_free_dev should have caught the NULL virt_dev pointer.

However, xhci_free_dev is designed to free the xhci_virt_device
structures, even if the host is dead, so that we don't leak kernel
memory.  xhci_free_dev checks the return value from the generic
xhci_check_args function.  If the return value is -ENODEV, it carries on
trying to free the virtual device.

The issue is that xhci_check_args looks at the host controller state
before it looks at the xhci_virt_device pointer.  It will return -ENIVAL
because the host is dead, and xhci_free_dev will ignore the return
value, and happily dereference the NULL xhci_virt_device pointer.

The fix is to make sure that xhci_check_args checks the xhci_virt_device
pointer before it checks the host state.

See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for
further details.  This patch doesn't solve the underlying issue, but
will ensure we don't see any more NULL pointer dereferences because of
the issue.

This patch should be backported to kernels as old as 3.1, that
contain the commit 7bd89b4017 "xhci: Don't
submit commands or URBs to halted hosts."

Ming Lei 10e232c597 USB: check sg buffer size in usb_submit_urb
USB spec stats that short packet can only appear at the end
of transfer. Because lost of HC(EHCI/UHCI/OHCI/...) can't
build a full packet from discontinuous buffers, we introduce
the limit in usb_submit_urb() to avoid such kind of bad sg buffers
coming from driver.

The limit might be a bit strict:
	- platform has iommu to do sg list mapping
	- some host controllers may support to build full packet from
	discontinuous buffers.

But considered that most of HCs don't support that, and driver
need work well or keep consistent on different HCs and ARCHs, we
have to introduce the limit.

Currently, only usbtest is reported to pass such sg buffers to HC,
and other users(mass storage, usbfs) don't have the problem.

We don't check it on USB wireless device, because:

In the spirit of "let's stop gossiping around the water cooler and get to work",
 here's some xHCI patches for 3.12.
 
 They include a patch for suspend/resume support for xhci platform hosts, two
 patches to support showing USB 2.1 link status, and a patch to future-proof the
 Intel EHCI to xHCI port switchover.

Greg Kroah-Hartman e45282829a USB: sl811: remove CONFIG_USB_DEBUG dependency
This removes the dependency of the driver on CONFIG_USB_DEBUG and moves
it to us the dynamic debug subsystem instead.  Bonus is the fact that we
can now properly determine the exact hardware that is spitting out the
messages.

This lets debugging be enabled without having to rebuild the driver, an
important thing for users that can not do it.

Greg Kroah-Hartman 457163c4c7 USB: ldusb: remove custom dbg_info() macro
We want to get rid of CONFIG_USB_DEBUG, so remove the reliance of the
ldusb driver on it.  Don't use the custom macro, or a special module
parameter, instead, rely on the in-kernel dynamic debugging
infrastructure, which is much easier to use, and consistant across the
whole kernel.

Mathias Nyman 26b76798e0 Intel xhci: refactor EHCI/xHCI port switching
Make the Linux xHCI driver automatically try to switchover the EHCI ports to
xHCI when an Intel xHCI host is detected, and it also finds an Intel EHCI host.

This means we will no longer have to add Intel xHCI hosts to a quirks list when
the PCI device IDs change.  Simply continuing to add new Intel xHCI PCI device
IDs to the quirks list is not sustainable.

During suspend ports may be swicthed back to EHCI by BIOS and not properly
restored to xHCI at resume. Previously both EHCI and xHCI resume functions
switched ports back to XHCI, but it's enough to do it in xHCI only
because the hub driver doesn't start running again until after both hosts are resumed.

Sarah Sharp 063ebeb433 xhci: Report USB 2.1 link status for L1
USB 2.1 devices can go into a lower power link state, L1.  When they are
active, they are in the L0 state.  The L1 transition can be purely
driven by software, or some USB host controllers (including some xHCI
1.0 hosts) allow the host hardware to track idleness and automatically
place a port into L1.

The USB 2.1 Link Power Management ECN gives a way for USB 2.1 hubs that
support LPM to report that a port is in L1.  The port status bit 5 will
be set when the port is in L1.  The xHCI host reports the root port as
being in 'U2' when the devices is in L1, and as being in 'U0' when the
port is active (in L0).

Translate the xHCI USB 2.1 link status into the format external hubs
use, and pass the L1 status up to the USB core and tools like lsusb.

Roger Quadros 47a64a13d5 USB: EHCI: Fix resume signalling on remote wakeup
Set the ehci->resuming flag for the port we receive a remote
wakeup on so that resume signalling can be completed.

Without this, the root hub timer will not fire again to check
if the resume was completed and there will be a never-ending wait on
on the port.

This effect is only observed if the HUB IRQ IN does not come after we
have initiated the port resume.

This patch was tested on 3.10.1 kernel.

Same models of Petatel NP10T modems have different device IDs.
Unfortunately they have no additional revision information on a board
which may treat them as different devices. Currently I've seen only
two NP10T devices with various IDs. Possibly Petatel NP10T list will
be appended upon devices with new IDs will appear.
