These cleanups are basically all over the place. The idea is to collect
changes with minimal impact but large number of changes so we can avoid
them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases.

Note this series is dependent upon a single target core patch for
adding se_cmd->unknown_data_length in target-pending/for-next, that

Let's have a unified table of RNDIS media. We used to have a similar
table with NDIS_* prefix from the gadget driver, but since we're only
using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows-
internal network drivers so what do we care) let's prefix everything
with RNDIS. Some of the definitions were conflicting, in one of the
defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took
the majority vote. Two definition of medium 0x09 calls it "wireless
WAN" but one vote for "wireless LAN" but in this case I am sticking
with the minority, "Wide Area Network" does not make much sense in
this case as far as I can tell.
NOTE: latin singular and plural is so screwed up in these defines
that it makes my eyes bleed. But I will not attempt to submit a
patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably
tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED
is most probably (erroneously) referring to a singular, unless it
can return an array of connected media. I suspect these erroneous
plurals are used in documentation and such so I don't want to
mess around with things for no functional change.

This patch (as1547) rearranges the Power Management parts of the
ehci-tegra driver to match the conventions used in other EHCI platform
drivers. In particular, the controller should not be powered down by
the root hub's suspend routine; the controller's power level should be
managed by the controller's own PM methods.
The end result of the patch is that the standard ehci_bus_suspend()
and ehci_bus_resume() methods can be used instead of special-purpose
routines. The driver now uses the standard dev_pm_ops methods instead
of legacy power management. Since there is no supported wakeup
mechanism for the controller, runtime suspend is forbidden by default
(this can be overridden via sysfs, if desired).
These adjustments are needed in order to make ehci-tegra compatible
with recent changes to the USB core. The core now checks the root
hub's status following bus suspend; if the controller is automatically
powered down during bus suspend then the check will fail and the root
hub will be resumed immediately. Doing the controller power-down in a
separate method avoids this problem.

It includes a couple of fixes to the ordering of the methods in udc-core.c.
Without these two patches, we will have issues when either unregistering a
gadget driver (triggered with dummy_hcd only) or issuing a device-initiated
disconnect through sysfs.
There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because
udc-core.c already handles that.
A fix to MUSB as promised, to kill the compile warnings regarding deprecated
interfaces. We are essentially dropping the __deprecated flag because it
doesn't look like we will ever be able to live without it when we consider the
amount of silicon issues we find on different MUSB instantiations.
A couple of other fixes are also available, one adding the missing transceiver
events to gpio_vbus and another adding a missing unregister call to MUSB's
davinci glue layer.

A couple of other fixes are also available, one adding the missing transceiver
events to gpio_vbus and another adding a missing unregister call to MUSB's

This patch (as1548) fixes a recently-introduced incompatibility
between the UDC core and the dummy-hcd driver. Commit
8ae8090c82 (usb: gadget: udc-core: fix
asymmetric calls in remove_driver) moved the usb_gadget_udc_stop()
call in usb_gadget_remove_driver() below the usb_gadget_disconnect()
call.
As a result, usb_gadget_disconnect() gets called at a time when the
gadget driver believes it has been unbound but dummy-hcd believes
it has not. A nasty error ensues when dummy-hcd calls the gadget
driver's disconnect method a second time.
To fix the problem, this patch moves the gadget driver's unbind
notification after the usb_gadget_disconnect() call. Now nothing
happens between the two unbind notifications, so nothing goes wrong.

This patch (as1545) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers. Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.
After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state. Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.
The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep. Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.
This fixes Bugzilla #42728.

This patch (as1544) fixes a problem affecting some EHCI controllers.
They can generate interrupts whenever the STS_FLR status bit is turned
on, even though that bit is masked out in the Interrupt Enable
register.
Since the driver doesn't use STS_FLR anyway, the patch changes the
interrupt routine to clear that bit whenever it is set, rather than
leaving it alone.

This patch (as1542) changes the criterion ehci-hcd uses to tell when
it needs to resume the controller's root hub. A resume is needed when
a port status change is detected, obviously, but only if the root hub
is currently suspended.
Right now the driver tests whether the root hub is running, and that
is not the correct test. In particular, if the controller has died
then the root hub should not be restarted. In addition, some buggy
hardware occasionally requires the root hub to be running and
sending out SOF packets even while it is nominally supposed to be
suspended.
In the end, the test needs to be changed. Rather than checking whether
the root hub is currently running, the driver will now check whether
the root hub is currently suspended. This will yield the correct
behavior in all cases.

This patch (as154) fixes a self-deadlock that occurs when userspace
writes to the bConfigurationValue sysfs attribute for a hub with
children. The task tries to lock the bandwidth_mutex at a time when
it already owns the lock:
The attribute's method calls usb_set_configuration(),
which calls usb_disable_device() with the bandwidth_mutex
held.
usb_disable_device() unregisters the existing interfaces,
which causes the hub driver to be unbound.
The hub_disconnect() routine calls hub_quiesce(), which
calls usb_disconnect() for each of the hub's children.
usb_disconnect() attempts to acquire the bandwidth_mutex
around a call to usb_disable_device().
The solution is to make usb_disable_device() acquire the mutex for
itself instead of requiring the caller to hold it. Then the mutex can
cover only the bandwidth deallocation operation and not the region
where the interfaces are unregistered.
This has the potential to change system behavior slightly when a
config change races with another config or altsetting change. Some of
the bandwidth released from the old config might get claimed by the
other config or altsetting, make it impossible to restore the old
config in case of a failure. But since we don't try to recover from
config-change failures anyway, this doesn't matter.
[This should be marked for stable kernels that contain the commit
fccf4e8620 "USB: Free bandwidth when
usb_disable_device is called."
That commit was marked for stable kernels as old as 2.6.32.]

It is observed that the echi ports of 3430 sdp board
are not working due to the random timing of programming
the associated GPIOs of the ULPI PHYs of the EHCI for reset.
If the PHYs are reset at during usbhs core driver, host ports will
not work because EHCI driver is loaded after the resetting PHYs.
The PHYs should be in reset state while initializing the EHCI
controller.
The code which does the GPIO pins associated with the PHYs
are programmed to reset is moved from the USB host core driver

For musb we have a fix for a kernel oops when unloading
omap2430.ko glue layer, proper error checking for pm_runtime_*,
fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
routine.
For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
allocation, TX FIFO corruption fix in DMA mode) but also a couple
of minor fixes (fixing maximum packet size for ep0 and fix for
big transfers with DMA).
For the dwc3 driver we have a memory leak fix, a very important
fix for USB30CV with SetFeature tests and the hability to handle
ep0 requests bigger than wMaxPacketSize.
On top of that there's a bunch of gadget driver minor fixes adding
proper section annotations, and fixing up the sysfs interface for
doing device-initiated connect/disconnect and so on.
All patches have been pending on the mailing list for quite a while
and look good for your for-linus branch.

The OMAP1 OHCI driver needs to enable the OCPI IP block before it can
work. Previously, the driver was simply calling a symbol defined in
the OMAP platform code, but this is incorrect: drivers should be fully
decoupled from platform and architecture code.
So instead, modify the driver to call through a platform_data function
pointer instead. We skip any DT aspect, since OMAP1 is not scheduled
to be converted to DT in the near future.
This resolves the following sparse warning:
It also gets rid of a cpu_is_omap16xx() call in a driver.
In the long term, it probably makes sense to move the OCPI bus code to
somewhere under drivers/. This should avoid the whole platform_data/DT
issue with this function.

The caller is allowed to specify the GFP flags for these functions.
We should prefer their flags unless we have good reason. For
example, if we take a spin_lock ourselves we'd need to use
GFP_ATOMIC. But in this case it's safe to use the callers GFP
flags.
The callers all pass GFP_ATOMIC here, so this change doesn't affect
how the kernel behaves but we may add other callers later and this
is a cleanup.

When the Seagate Goflex USB3.0 device is attached to VIA xHCI
host, sometimes the device will downgrade mode to high speed.
By the USB analyzer, I found the device finished the link
training process and worked at superspeed mode. But the device
descriptor got from the device shows the device works at 2.1.
It is very strange and seems like the device controller of
Seagate Goflex has a little confusion.
The first 8 bytes of device descriptor should be:
12 01 00 03 00 00 00 09
But the first 8 bytes of wrong device descriptor are:
12 01 10 02 00 00 00 40
The wrong device descriptor caused the initialization of mass
storage failed. After a while, the device would be recognized
as a high speed device and works fine.
This patch will warm reset the device to fix the issue after
finding the bcdUSB field of device descriptor isn't 0x0300
but the speed mode of device is superspeed.
This patch should be backported to kernels as old as 3.2, or ones that
contain the commit 75d7cf72ab "usbcore:
refine warm reset logic".
