The BDC endpoint status registers 0-7 were originally each going
to be an array of regsiters. This was later changed to being a
single register. The register definitions are being changed from:
"#define BDC_EPSTS0(n) (0x60 + (n * 0x10))"
to
"#define BDC_EPSTS0 0x60"
to reflect this change and to avoid future coding mistakes.

This adds 3 new options to the RNDIS gadget function configs. It allows
overriding the default USB interface class/subclass/protocol.
The motivation for this is that if you set the values to "ef" (Misc),
"04" (RNDIS), "01" (Ethernet) respectively, then the device will be
recognized by the rndiscmp.inf file in Windows Vista and newer and will
cause Windows to load the correct RNDIS driver without the need for a
custom (signed) .inf file.

In the SG case this is already handled since a non-zero
request->num_mapped_sgs is a clear indicator that dma_map_sg()
had been called. While it would be nice to do the same for the
singly mapped case by simply checking for non-zero request->dma,
it's conceivable that 0 is a valid dma_addr_t handle. Hence add
a flag 'dma_mapped' to struct usb_request and use this to
determine the need to call dma_unmap_single(). Otherwise, if a
request is not DMA mapped then the result of calling
usb_request_unmap_request() would safely be a no-op.

Currenly, f_midi_free uses snd_card_free, which will wait
until the user has released the sound card before
returning. However, if the user doesn't release the sound
card, then f_midi_free can block for an arbitrary amount
of time, which also blocks any gadget operations on that
thread.
Instead, we can use snd_card_free_when_closed which returns
before all handles are released. Since f_midi can be
accessed through rmidi if usb_put_function is called before
release_card_device, add refcounting to f_midi_free and
have rawmidi's private free call it. The f_midi memory
is only kfreed when usb_put_function and release_card_device
have both been called.

Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure. This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.
The logic for doing this is careful to check that the device is still
connected. But this check is inadequate if the device disconnects and
reconnects before the check is done. The symptom is that a device
works, but much more slowly than it is capable of operating.
The situation was made worse recently by commit 22547c4cc4 ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.
This patch makes the check more robust. If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume
On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.
In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.
As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

Another fix for isochronous transfers on dwc3. This time around, we're
making sure that we use correct PIDs in all transfer sizes.
MSM PHY driver got a fix for the use of devm_regulator_bulk_get() API
which will avoid kernel crashes.
Renesas DRD driver got 3 fixes: a fix on giveback, a fix for proper
controller programming and the removal of set-but-never-used variable.
The commit b8b9c974af ("usb: renesas_usbhs: gadget: disable all eps
when the driver stops") causes the unused-but-set-variable warning.
But, if the usbhsg_ep_disable() will return non-zero value, udc/core.c
doesn't clear the ep->enabled flag. So, this driver should not return
non-zero value, if the pipe is zero because this means the pipe is
already disabled. Otherwise, the ep->enabled flag is never cleared
when the usbhsg_ep_disable() is called by the renesas_usbhs driver first.

The latest HW manual (Rev.0.55) shows us this UGCTRL2.VBUSSEL bit.
If the bit sets to 1, the VBUS drive is controlled by phy related
registers (called "UCOM Registers" on the manual). Since R-Car Gen3
environment will control VBUS by phy-rcar-gen3-usb2 driver,
the UGCTRL2.VBUSSEL bit should be set to 1. So, this patch fixes
the register's value. Otherwise, even if the ID pin indicates to
peripheral, the R-Car will output USBn_PWEN to 1 when a host driver
is running.

The regulator_bulk_data pointer passed to devm_regulator_bulk_get()
is used to store the client handles for the regulators, which
is later used by devm_regulator_bulk_release() to free the
regulators.
Passing a local array as is done here means the memory used to
store the handles is freed causing the handles to be corrupted,
resulting in a crash when devm_regulator_bulk_release() tries to
free them.

According to the gadget.h, a "complete" function will always be called
with interrupts disabled. However, sometimes usb3_request_done() function
is called with interrupts enabled. So, this function should be held
by spin_lock_irqsave() to disable interruption. Also, this driver has
to call spin_unlock() to avoid spinlock recursion by this driver before
calling usb_gadget_giveback_request().

The PIDs for Isochronous data transfers are incorrect
for high bandwidth IN endpoints when the request length
is less than EP wMaxPacketSize.
As per spec correct PIDs for ISOC data transfers are:
1) For request length <= maxpacket
- DATA0,
2) For maxpacket < length <= (2 * maxpacket)
- DATA1, DATA0
3) For (2 * maxpacket) < length <= (3 * maxpacket)
- DATA2, DATA1, DATA0.
But driver always sets PCM fields based on wMaxPacketSize
due to which DATA2 happens even for small requests.
Fix this by setting the PCM field of trb->size depending
on request length rather than fixing it to the value
depending on wMaxPacketSize.
Ideally it shouldn't give any issues as dwc3 will send
0-length packet for next IN token if host sends (even
after receiving a short packet). Windows seems to ignore
this but with MacOS frame loss observed when using f_uvc.

The Renesas uPD72020x XHCI controller seems to suffer from a really
annoying bug, where it may retain some of its DMA programming across a XHCI
reset, and despite the driver correctly programming new DMA addresses.
This is visible if the device has been using 64-bit DMA addresses, and is
then switched to using 32-bit DMA addresses. The top 32 bits of the
address (now zero) are ignored are replaced by the 32 bits from the
*previous* programming. Sticking with 64-bit DMA always works, but doesn't
seem very appropriate.
A PCI reset of the device restores the normal functionality, which is done
at probe time. Unfortunately, this has to be done before any quirk has
been discovered, hence the intrusive nature of the fix.

commit 68fe05e2a4 ("usb: musb: fix tx fifo flush handling") drops the
1ms delay trying to solve the long disconnect time issue when
application queued many tx urbs. However, the 1ms delay is needed for
some use cases, for example, without the delay, reconnecting AR9271 WIFI
dongle no longer works if the connection is dropped from the AP.
So let's add back the 1ms delay in musb_h_tx_flush_fifo(), and solve the
long disconnect time problem with a separate patch for
usb_hcd_flush_endpoint().

While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.
Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.
This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

Christoph Hellwig says that since version 4.12, the kernel switched to
using blk-mq by default. The old code used a softirq for handling
request completions, but blk-mq can handle completions in the caller's
context. This may cause a problem for usb-storage, because it invokes
the ->scsi_done callback while holding the host lock, and the
completion routine sometimes tries to acquire the same lock (when
running the error handler, for example).
The consequence is that the existing code will sometimes deadlock upon
error completion of a SCSI command (with a lockdep warning).
This is easy enough to fix, since usb-storage doesn't really need to
hold the host lock while the callback runs. It was simpler to write
it that way, but moving the call outside the locked region is pretty
easy and there's no downside. That's what this patch does.

Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared

Among other thigs, this prevents check_root_hub_suspended() from

A uncleared PLC (port link change) bit will prevent furuther port event
interrupts for that port. Leaving it uncleared caused get_port_status()
to timeout after 20000ms while waiting to get the final port event
interrupt for resume -> U0 state change.
This is a targeted fix for a specific case where we get a port resume event
racing with xhci resume. The port event interrupt handler notices xHC is
not yet running and bails out early, leaving PLC uncleared.
The whole xhci port resuming needs more attention, but while working on it
it anyways makes sense to always ensure PLC is cleared in get_port_status
before setting a new link state and waiting for its completion.

on AMD platforms with SNPS 3.1 USB controller if stop endpoint command is
issued the controller does not respond, when the EP is not in running
state. HW completes the command execution and reports
"Context State Error" completion code. This is as per the spec. However
HW on receiving the second command additionally marks EP to Flow control
state in HW which is RTL bug. This bug causes the HW not to respond
to any further doorbells that are rung by the driver. This makes the EP
to not functional anymore and causes gross functional failures.
As a workaround, not to hit this problem, it's better to check the EP state
and issue a stop EP command only when the EP is in running state.
As a sidenote, even with this patch there is still a possibility of
triggering the RTL bug if the context state races with the stop endpoint
command as described in xHCI spec 4.6.9

A gadget driver will not disable eps immediately when ->disconnect()
is called. But, since this driver assumes all eps stop after
the ->disconnect(), unexpected behavior happens (especially in system
suspend).
So, this patch disables all eps in usbhsg_try_stop(). After disabling
eps by renesas_usbhs driver, since some functions will be called by
both a gadget and renesas_usbhs driver, renesas_usbhs driver should
protect uep->pipe. To protect uep->pipe easily, this patch adds a new
lock in struct usbhsg_uep.

This patch fixes an issue that some registers may be not initialized
after resume if the USBHSF_RUNTIME_PWCTRL is not set. Otherwise,
if a cable is not connected, the driver will not enable INTENB0.VBSE
after resume. And then, the driver cannot detect the VBUS.

This patch fixes an issue that unexpected behavior happens when
both the interrupt handler and renesas_usb3_ep_enable() are called.
In this case, since usb3_start_pipen() checked the usb3_ep->started,
but the flags was not protected. So, this patch protects the flag
by usb3->lock. Since renesas_usb3_ep_enable() for EP0 will be not called,
this patch doesn't take care of usb3_start_pipe0().

A recent optimization was made so that a request put on the
pending_list wouldn't get mapped for DMA until just before
preparing a TRB for it. However, this poses a problem in case
the request is dequeued or the endpoint is disabled before the
mapping is done as that would lead to dwc3_gadget_giveback()
unconditionally calling usb_gadget_unmap_request_for_dev() with
an invalid request->dma handle. Depending on the platform's DMA
implementation the unmap operation could result in a panic.
Since we know a successful mapping is a prerequisite for getting
a TRB, the unmap can be conditionally called only when req->trb
is non-NULL.

IRQ_NOAUTOEN cannot be used with shared IRQs, since commit 04c848d398
("genirq: Warn when IRQ_NOAUTOEN is used with shared interrupts") and
kernel now throws a warn dump. But OMAP DWC3 driver uses this flag. As
per commit 12a7f17fac ("usb: dwc3: omap: fix race of pm runtime with
irq handler in probe") that introduced this flag, PM runtime can race
with IRQ handler when deferred probing happens due to extcon,
therefore IRQ_NOAUTOEN needs to be set so that irq is not enabled until
extcon is registered.
Remove setting of IRQ_NOAUTOEN and move the registration of
shared irq to a point after dwc3_omap_extcon_register() and
of_platform_populate(). This avoids possibility of probe deferring and
above said race condition.

This development cycle resulted in a fair amount of changes in both
core and driver sides. The most significant change in ALSA core is
about PCM. Also the support of of-graph card and the new DAPM widget
for DSP are noteworthy changes in ASoC core. And there're lots of
small changes splat over the tree, as you can see in diffstat.
Below are a few highlights:
ALSA core:
- Removal of set_fs() hackery from PCM core stuff, and the code
reorganization / optimization thereafter
- Improved support of PCM ack ops, and a new ABI for improved
control/status mmap handling
- Lots of constifications in various codes
ASoC core:
- The support of of-graph card, which may work as a better generic
device for a replacement of simple-card
- New widget types intended mainly for use with DSPs
ASoC drivers:
- New drivers for Allwinner V3s SoCs
- Ensonic ES8316 codec support
- More Intel SKL and KBL works
- More device support for Intel SST Atom (mostly for cheap tablets and
2-in-1 devices)
- Support for Rockchip PDM controllers
- Support for STM32 I2S and S/PDIF controllers
- Support for ZTE AUD96P22 codecs
HD-audio:
- Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
for HP and Dell machines
- A few more fixes for i915 component binding
Note that of-graph change may bring the conflicts with a later pull
request of devicetree, as currently found in linux-next.

- Rework suspend-to-idle to allow it to take wakeup events signaled
by the EC into account on ACPI-based platforms in order to properly
support power button wakeup from suspend-to-idle on recent Dell
laptops (Rafael Wysocki).
That includes the core suspend-to-idle code rework, support for
the Low Power S0 _DSM interface, and support for the ACPI INT0002
Virtual GPIO device from Hans de Goede (required for USB keyboard
wakeup from suspend-to-idle to work on some machines).
- Stop trying to export the current CPU frequency via /proc/cpuinfo
on x86 as that is inaccurate and confusing (Len Brown).
- Rework the way in which the current CPU frequency is exported by
the kernel (over the cpufreq sysfs interface) on x86 systems with
the APERF and MPERF registers by always using values read from
these registers, when available, to compute the current frequency
regardless of which cpufreq driver is in use (Len Brown).
- Rework the PCI/ACPI device wakeup infrastructure to remove the
questionable and artificial distinction between "devices that
can wake up the system from sleep states" and "devices that can
generate wakeup signals in the working state" from it, which
allows the code to be simplified quite a bit (Rafael Wysocki).
- Fix the wakeup IRQ framework by making it use SRCU instead of
RCU which doesn't allow sleeping in the read-side critical
sections, but which in turn is expected to be allowed by the
IRQ bus locking infrastructure (Thomas Gleixner).
- Modify some computations in the intel_pstate driver to avoid
rounding errors resulting from them (Srinivas Pandruvada).
- Reduce the overhead of the intel_pstate driver in the HWP
(hardware-managed P-states) mode and when the "performance"
P-state selection algorithm is in use by making it avoid
registering scheduler callbacks in those cases (Len Brown).
- Rework the energy_performance_preference sysfs knob in
intel_pstate by changing the values that correspond to
different symbolic hint names used by it (Len Brown).
- Make it possible to use more than one cpuidle driver at the same
time on ARM (Daniel Lezcano).
- Make it possible to prevent the cpuidle menu governor from using
the 0 state by disabling it via sysfs (Nicholas Piggin).
- Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1
on AMD systems (Yazen Ghannam).
- Make the CPPC cpufreq driver take the lowest nonlinear performance
information into account (Prashanth Prakash).
- Add support for hi3660 to the cpufreq-dt driver, fix the
imx6q driver and clean up the sfi, exynos5440 and intel_pstate
drivers (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila,
Rafael Wysocki, Tao Wang).
- Fix a few minor issues in the generic power domains (genpd)
framework and clean it up somewhat (Krzysztof Kozlowski,
Mikko Perttunen, Viresh Kumar).
- Fix a couple of minor issues in the operating performance points
(OPP) framework and clean it up somewhat (Viresh Kumar).
- Fix a CONFIG dependency in the hibernation core and clean it up
slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
- Add rk3228 support to the rockchip-io adaptive voltage scaling
(AVS) driver (David Wu).
- Fix an incorrect bit shift operation in the RAPL power capping
driver (Adam Lessnau).
- Add support for the EPP field in the HWP (hardware managed
P-states) control register, HWP.EPP, to the x86_energy_perf_policy
tool and update msr-index.h with HWP.EPP values (Len Brown).
- Fix some minor issues in the turbostat tool (Len Brown).
- Add support for AMD family 0x17 CPUs to the cpupower tool and fix
a minor issue in it (Sherry Hurwitz).
- Assorted cleanups, mostly related to the constification of some
data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
Kozlowski).

Pull power management updates from Rafael Wysocki:
"The big ticket items here are the rework of suspend-to-idle in order
to add proper support for power button wakeup from it on recent Dell
laptops and the rework of interfaces exporting the current CPU
frequency on x86.
In addition to that, support for a few new pieces of hardware is
added, the PCI/ACPI device wakeup infrastructure is simplified
significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
bus locking infrastructure.
Also, there are some functional improvements for intel_pstate, tools
updates and small fixes and cleanups all over.

Here is the big driver core update for 4.13-rc1.
The large majority of this is a lot of cleanup of old fields in the
driver core structures and their remaining usages in random drivers.
All of those fixes have been reviewed by the various subsystem
maintainers. There's also some small firmware updates in here, a new
kobject uevent api interface that makes userspace interaction easier,
and a few other minor things.
All of these have been in linux-next for a long while with no reported
issues.

by Morimoto-san.
- New widget types intended mainly for use with DSPs.
- New drivers for Allwinner V3s SoCs, Ensonic ES8316, several classes

Merge tag 'uuid-for-4.13' of git://git.infradead.org/users/hch/uuid
Pull uuid subsystem from Christoph Hellwig:
"This is the new uuid subsystem, in which Amir, Andy and I have started
consolidating our uuid/guid helpers and improving the types used for
them. Note that various other subsystems have pulled in this tree, so
I'd like it to go in early.
UUID/GUID summary:
- introduce the new uuid_t/guid_t types that are going to replace the
somewhat confusing uuid_be/uuid_le types and make the terminology
fit the various specs, as well as the userspace libuuid library.
(me, based on a previous version from Amir)
- consolidated generic uuid/guid helper functions lifted from XFS and
libnvdimm (Amir and me)
- conversions to the new types and helpers (Amir, Andy and me)"

The USB core and sysfs will attempt to enumerate certain parameters
which are unsupported by the au0828 - causing inconsistent behavior
and sometimes causing the chip to reset. Avoid making these calls.
This problem manifested as intermittent cases where the au8522 would
be reset on analog video startup, in particular when starting up ALSA
audio streaming in parallel - the sysfs entries created by
snd-usb-audio on streaming startup would result in unsupported control
messages being sent during tuning which would put the chip into an
unknown state.

Rework smelling code (goto inside compound statement). Perhaps this is
legacy. Anyway such code is not appropriate for Linux kernel.
