Now we are sure that, if res_trans_idx is zero, then endpoint has been
stopped. So it's safe to just return if endpoint is already stopped. No
need to generate warning anymore.
While doing so, it's better to return when res_trans_idx is zero and
decrease one level of indentation.

By the time we're disabling the endpoint, HW
could already have posted more events to our
event buffer. In that case, we will receive
endpoint events for a disabled endpoint.
In order to protect ourselves from that situation,
we simply ignore endpoint interrupts whenever
the endpoint is disabled.

In case we get disconnected, we will call gadget

Currently in case of isoc, interrupt is programmed after each
TRB_NUM/4 ie 8th TRB. A TRB is programmed against each submitted
request from gadget. If we do not want to limit the minimum number of
necessary request to be submitted from gadget then we must receive
interrupt on each TRB submission. There can be such situation with a
gadget working with ping-pong buffer.
If a gadget does not want to receive interrupt after each request
completion then it may set no_interrupt flag.

According to the databook, the DWC3 Core will
reset those bits to 0 on USB Bus Reset. This
means we must re-enable those bits on every

Because we will always get a Reset interrupt

of re-enabling something that was just lost,
move the handling of those bits to the Reset
Interrupt.

days ago, but those were fixed by the most recent changes (all were
due to us not building with CONFIG_PM disabled.)

With this, five platforms are moving to the relatively new pinctrl
subsystem for their pin management, replacing the older soc specific
in-kernel interfaces with common code.
There is quite a bit of net addition of code for each platform being
added to the pinctrl subsystem. but the payback comes later when adding
new boards can be done by only providing new device trees instead.

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.

Pull usb-gadget scsi-target merge from Nicholas Bellinger:
"As promised, here is the pull request for Sebastian's usb-gadget
target UASP / BOT driver for v3.5-rc1. This code has been in
linux-next for a number of weeks, and is now ready for an initial
merge.
This fabric uses the target framework to provide a usb gadget device.
This gadget supports the USB Attached SCSI Protocol (UASP) and Bulk
Only Transfers (BOT or BBB). BOT is the primary interface, UAS is the
alternative interface.
Note this series is dependent upon a single target core patch for
adding se_cmd->unknown_data_length in target-pending/for-next, that
got merged in the parent.
Kudos to Sebastian for making this driver happen so easily, and for
his patches to improve usb-core and target core along the way to his
goal. Also thanks to Felipe + Greg-KH for their help in getting this
driver ready for mainline."

xhci/usb: Build error fixes for 3.5
Hi Greg,
Here's four patches that fix the build errors introduced by the USB 3.0 Link PM
patches. Please pull for inclusion in 3.5.

Fengguang reports that the xHCI driver isn't linked properly on his
machine:
ERROR: "__udivdi3" [drivers/usb/host/xhci-hcd.ko] undefined!
ERROR: "handle_edge_irq" [drivers/gpio/gpio-pch.ko] undefined!
ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined!
The driver compiles fine on my 64-bit box (gcc version 4.6.1).
Fengguang thinks it's because the xHCI driver was using DIV_ROUND_UP()
instead of DIV_ROUND_UP_ULL() with arguments that were unsigned long
long variables.

The USB 2.0 Link PM code is conditionally compiled when
CONFIG_USB_SUSPEND=y. I believe that's a mistake, since Link PM is not
directly related to USB device suspend and Link PM is implemented
without relying on any of the suspend code in the USB core. For now,
keep the USB 2.0 Link PM code conditionally compiled if
CONFIG_USB_SUSPEND=y.
This patch does move the code to implement USB 3.0 Link PM out of the
xHCI driver #ifdefs for CONFIG_USB_SUSPEND and moves it into a section
dependent on CONFIG_PM. The USB core functions for USB 3.0 Link PM are
already conditionally compiled when CONFIG_PM=y.
