Amardeep Rai d8fd7d5ae3 usb: spear-ehci/ohci: Do clk_get using dev-id
We used to get clk using con-id, but now we have device struct available for
these devices as they are probed using DT. And so must get clk using dev-id.

Greg Kroah-Hartman 51f1206f60 xHCI patches for 3.8
Hi Greg,
 
 Here's some xHCI bug fixes.  There's nothing major in here that can't
 wait for 3.8.  The NULL pointer deref that commit 68e5254 fixes hasn't
 ever been reported in the three years that the xHCI driver has been
 available, so it can wait a few more weeks.
 
 There's two quirk updates, one for Fresco Logic (commit bba18e3) and one
 for xHCI hosts with the TI redriver (commit b0e4e60).  Commit 4525c0a
 makes the xHCI driver work correctly on the SiBridge xHCI host (and
 perhaps other 1.0 xHCI host controllers).  Commit 392a07a fixes a bug in
 the Intel Panther Point xHCI host bandwidth checking checking.
 
 Commits 2611bd1 and 77b8476 are trivial cleanup patches.

Sarah Sharp bba18e33f2 xhci: Extend Fresco Logic MSI quirk.
Ali reports that plugging a device into the Fresco Logic xHCI host with
PCI device ID 1400 produces an IRQ error:

 do_IRQ: 3.176 No irq handler for vector (irq -1)

Other early Fresco Logic host revisions don't support MSI, even though
their PCI config space claims they do.  Extend the quirk to disabling
MSI to this chipset revision.  Also enable the short transfer quirk,
since it's likely this revision also has that quirk, and it should be
harmless to enable.

Julius Werner 68e5254adb xhci: fix null-pointer dereference when destroying half-built segment rings
xhci_alloc_segments_for_ring() builds a list of xhci_segments and links
the tail to head at the end (forming a ring). When it bails out for OOM
reasons half-way through, it tries to destroy its half-built list with
xhci_free_segments_for_ring(), even though it is not a ring yet. This
causes a null-pointer dereference upon hitting the last element.

Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes
the output parameters to be valid upon this kind of OOM failure, and
calls xhci_ring_free() on them. Since the (incomplete) list/ring should
already be destroyed in that case, this would lead to a use after free.

This patch fixes those issues by having xhci_alloc_segments_for_ring()
destroy its half-built, non-circular list manually and destroying the
invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree().

This patch should be backported to kernels as old as 2.6.31, that
contains the commit 0ebbab3742 "USB: xhci:
Ring allocation and initialization."

A separate patch will need to be developed for kernels older than 3.4,
since the ring allocation code was refactored in that kernel.

Sarah Sharp 4525c0a10d xHCI: Fix TD Size calculation on 1.0 hosts.
The xHCI 1.0 specification made a change to the TD Size field in TRBs.
The value is now the number of packets that remain to be sent in the TD,
not including this TRB.  The TD Size value for the last TRB in a TD must
always be zero.

The xHCI function xhci_v1_0_td_remainder() attempts to calculate this,
but it gets it wrong.  First, it erroneously reuses the old
xhci_td_remainder function, which will right shift the value by 10.  The
xHCI 1.0 spec as of June 2011 says nothing about right shifting by 10.
Second, it does not set the TD size for the last TRB in a TD to zero.

Third, it uses roundup instead of DIV_ROUND_UP.  The total packet count
is supposed to be the total number of bytes in this TD, divided by the
max packet size, rounded up.  DIV_ROUND_UP is the right function to use
in that case.

With the old code, a TD on an endpoint with max packet size 1024 would
be set up like so:
TRB 1, TRB length = 600 bytes, TD size = 0
TRB 1, TRB length = 200 bytes, TD size = 0
TRB 1, TRB length = 100 bytes, TD size = 0

With the new code, the TD would be set up like this:
TRB 1, TRB length = 600 bytes, TD size = 1
TRB 1, TRB length = 200 bytes, TD size = 1
TRB 1, TRB length = 100 bytes, TD size = 0

This commit should be backported to kernels as old as 3.0, that contain
the commit 4da6e6f247 "xhci 1.0: Update TD
size field format."

Sarah Sharp 392a07ae33 xhci: Fix conditional check in bandwidth calculation.
David reports that at drivers/usb/host/xhci.c:2257:

static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
    return (ep_type == ISOC_IN_EP || ep_type != INT_IN_EP);
}

The static analyser cppcheck says

[linux-3.7-rc2/drivers/usb/host/xhci.c:2257]: (style) Redundant condition: If ep_type == 5, the comparison ep_type != 7 is always true.

Maybe the original programmer intention was something like

static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
    return (ep_type == ISOC_IN_EP || ep_type == INT_IN_EP);
}

Fix this.

Alan Stern 2656a9abcf USB: EHCI: bugfix: urb->hcpriv should not be NULL
This patch (as1632b) fixes a bug in ehci-hcd.  The USB core uses
urb->hcpriv to determine whether or not an URB is active; host
controller drivers are supposed to set this pointer to a non-NULL
value when an URB is queued.  However ehci-hcd sets it to NULL for
isochronous URBs, which defeats the check in usbcore.

In itself this isn't a big deal.  But people have recently found that
certain sequences of actions will cause the snd-usb-audio driver to
reuse URBs without waiting for them to complete.  In the absence of
proper checking by usbcore, the URBs get added to their endpoint list
twice.  This leads to list corruption and a system freeze.

The patch makes ehci-hcd assign a meaningful value to urb->hcpriv for
isochronous URBs.  Improving robustness always helps.

This patch (as1630) cleans up a few minor items resulting from the

	Remove the product_desc string from the ehci_driver_overrides

	Controller" string.  (This was requested by Felipe Balbi.)

	Allow drivers to pass a NULL pointer to ehci_init_driver()
	if they don't have to override any settings.

	Remove a #define symbol that is no longer used from the
	ChipIdea host driver.

	Rename overrides to pci_overrides in ehci-pci.c, for
	consistency with ehci-platform.c.

	Mark the *_overrides structures as __initdata.

Alan Stern 36caff5d79 USB: fix endpoint-disabling for failed config changes
This patch (as1631) fixes a bug that shows up when a config change
fails for a device under an xHCI controller.  The controller needs to
be told to disable the endpoints that have been enabled for the new
config.  The existing code does this, but before storing the
information about which endpoints were enabled!  As a result, any
second attempt to install the new config is doomed to fail because
xhci-hcd will refuse to enable an endpoint that is already enabled.

The patch optimistically initializes the new endpoints' device
structures before asking the device to switch to the new config.  If
the request fails then the endpoint information is already stored, so
we can use usb_hcd_alloc_bandwidth() to disable the endpoints with no
trouble.  The rest of the error path is slightly more complex now; we
have to disable the new interfaces and call put_device() rather than
simply deallocating them.

 There's a big series getting us closer to being able to

 Other than that there's the usual typo fixes and miscelaneous

Greg Kroah-Hartman 0f89fc3fd8 usb: dwc3: patches for v3.8
We can finaly drop HAVE_CLK dependency from exynos glue layer
 now that clk API provides no-op stubs when it's not linked
 into the kernel.
 
 We're also switching over event buffer allocation to devm_kzalloc()
 and moving the allocation out of dwc3_core_init() so that can be
 re-used when implementing PM support for v3.9.
 
 After the introduction of PLATFORM_DEVID_AUTO, we can also drop the
 homebrew platform device ID handling we had on dwc3 core and let
 driver core take care of that for us.
 
 Exynos glue layer learns about DeviceTree and drops platform_data
 support completely.

USB dwc3 patches from Felipe:

"usb: dwc3: patches for v3.8

We can finaly drop HAVE_CLK dependency from exynos glue layer
now that clk API provides no-op stubs when it's not linked
into the kernel.

We're also switching over event buffer allocation to devm_kzalloc()
and moving the allocation out of dwc3_core_init() so that can be
re-used when implementing PM support for v3.9.

After the introduction of PLATFORM_DEVID_AUTO, we can also drop the
homebrew platform device ID handling we had on dwc3 core and let
driver core take care of that for us.

Exynos glue layer learns about DeviceTree and drops platform_data
support completely."

Greg Kroah-Hartman 3a3f2e5095 usb: musb: patches for v3.8 merge window
We have here the usual set of cleanups for the MUSB driver; a
 big set of patches converting platform_device_del() and
 platform_device_put() into platform_device_unregister().
 
 Another big set was applied converting to module_platform_driver()
 macro in order to reduce some boilerplate code from all glue
 layers.
 
 Other than that, we had a series fixing one known silicon errata
 where we couldn't read a few registers. In order to fix that
 we're now using shadow variables for reads and only writing
 to the registers which are known to break functionality when
 read.

 "Bug fixes galore, mostly in drivers as is often the case:

  1) USB gadget and cdc_eem drivers need adjustments to their frame size
     lengths in order to handle VLANs correctly.  From Ian Coolidge.

  2) TIPC and several network drivers erroneously call tasklet_disable
     before tasklet_kill, fix from Xiaotian Feng.

  3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
     fix from Cyril Brulebois.

  4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
     Nathan Walp.

  5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
     zero.  From John Fastabend.

  6) Fix smsc95xx tx checksum offload on big-endian, from Steve
     Glendinning.

  7) __inet_diag_dump() needs to repsect and report the error value
     returned from inet_diag_lock_handler() rather than ignore it.
     Otherwise if an inet diag handler is not available for a particular
     protocol, we essentially report success instead of giving an error
     indication.  Fix from Cyrill Gorcunov.

  8) When the QFQ packet scheduler sees TSO/GSO packets it does not
     handle things properly, and in fact ends up corrupting it's
     datastructures as well as mis-schedule packets.  Fix from Paolo
     Valente.

  9) Fix oopser in skb_loop_sk(), from Eric Leblond.

  10) CXGB4 passes partially uninitialized datastructures in to FW
      commands, fix from Vipul Pandya.

  11) When we send unsolicited ipv6 neighbour advertisements, we should
      send them to the link-local allnodes multicast address, as per
      RFC4861.  Fix from Hannes Frederic Sowa.

  12) There is some kind of bug in the usbnet's kevent deferral
      mechanism, but more immediately when it triggers an uncontrolled
      stream of kernel messages spam the log.  Rate limit the error log
      message triggered when this problem occurs, as sending thousands
      of error messages into the kernel log doesn't help matters at all,
      and in fact makes further diagnosis more difficult.

      From Steve Glendinning.

  13) Fix gianfar restore from hibernation, from Wang Dongsheng.

  14) The netlink message attribute sizes are wrong in the ipv6 GRE
      driver, it was using the size of ipv4 addresses instead of ipv6
      ones :-) Fix from Nicolas Dichtel."

We tried linking in a single built object to hold the device table,

Just include the device ID stub into each driver source file so that

Andreas Larsson 0bce04be44 of/address: sparc: Declare of_address_to_resource() as an extern function for sparc again
This bug-fix makes sure that of_address_to_resource is defined extern for sparc
so that the sparc-specific implementation of of_address_to_resource() is once
again used when including include/linux/of_address.h in a sparc context. A
number of drivers in mainline relies on this function working for sparc.

The bug was introduced in a850a75544, "of/address:
add empty static inlines for !CONFIG_OF". Contrary to that commit title, the
static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never
defined for sparc. This is good behavior for the other functions in
include/linux/of_address.h, as the extern functions defined in
drivers/of/address.c only gets linked when OF_ADDRESS is configured. However,
for of_address_to_resource there exists a sparc-specific implementation in
arch/sparc/arch/sparc/kernel/of_device_common.c

This adds sparc support for platform_get_irq that in the normal case use

Wang Dongsheng 103cdd1d59 gianfar: ethernet vanishes after restoring from hibernation
If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.

For example:

	~# ifconfig eth0 down
	~# echo disk > /sys/power/state

	  <trigger a restore from hibernation>

	~# ifconfig eth0 up
	SIOCSIFFLAGS: No such device

This happens because the restore function bails out early upon
finding devices that were not up at hibernation.  In doing so,
it never gets to the netif_device_attach call at the end of
the restore function.  Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

The commit 911dec0db4
"xen/arm: Fix compile errors when drivers are compiled as modules." exports
the neccessary functions. But to guard ourselves against out-of-tree modules
and future drivers hitting this, lets export all of the relevant
hypercalls.

This reverts commit d8c3ef256f.

Above mentioned change was made along with multi usb phy change and
adding DT support for nop transceiver. But other two changes did not
make it to mainline. This in effect makes dsps musb wrapper unusable
even for single instance.

Hence revert it so that at least single instance can be supported.
