Macpaul Lin 456244aeec usb: mtu3: fix USB 3.0 dual-role-switch from device to host
Issue description:
  When an OTG port has been switched to device role and then switch back
  to host role again, the USB 3.0 Host (XHCI) will not be able to detect
  "plug in event of a connected USB 2.0/1.0 ((Highspeed and Fullspeed)
  devices until system reboot.

Root cause and Solution:
  There is a condition checking flag "ssusb->otg_switch.is_u3_drd" in
  toggle_opstate(). At the end of role switch procedure, toggle_opstate()
  will be called to set DC_SESSION and SOFT_CONN bit. If "is_u3_drd" was
  set and switched the role to USB host 3.0, bit DC_SESSION and SOFT_CONN
  will be skipped hence caused the port cannot detect connected USB 2.0
  (Highspeed and Fullspeed) devices. Simply remove the condition check to
  solve this issue.

Minghao Chi 5bf4b20dc1 usb:oxu210hp-hcd: Use platform_get_irq() to get the interrupt
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.

platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.

It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

Christophe Leroy eafc69a488 usb: Prepare cleanup of powerpc's asm/prom.h
powerpc's asm/prom.h brings some headers that it doesn't
need itself.

In order to clean it up in a further step, first clean all
files that include asm/prom.h

Some files don't need asm/prom.h at all. For those ones,
just remove inclusion of asm/prom.h

Some files don't need any of the items provided by asm/prom.h,
but need some of the headers included by asm/prom.h. For those
ones, add the needed headers that are brought by asm/prom.h at
the moment, then remove asm/prom.h

Some files really need asm/prom.h but also need some of the
headers included by asm/prom.h. For those one, leave asm/prom.h
but also add the needed headers so that they can be removed
from asm/prom.h in a later step.

Niels Dossche d088fabace usb: usbip: add missing device lock on tweak configuration cmd
The function documentation of usb_set_configuration says that its
callers should hold the device lock. This lock is held for all
callsites except tweak_set_configuration_cmd. The code path can be
executed for example when attaching a remote USB device.
The solution is to surround the call by the device lock.

This bug was found using my experimental own-developed static analysis
tool, which reported the missing lock on v5.17.2. I manually verified
this bug report by doing code review as well. I runtime checked that
the required lock is not held. I compiled and runtime tested this on
x86_64 with a USB mouse. After applying this patch, my analyser no
longer reports this potential bug.

Peter Geis 4e64cd7763 usb: dwc3: fix backwards compat with rockchip devices
Commit 33fb697ec7 ("usb: dwc3: Get clocks individually") moved from
the clk_bulk api to individual clocks, following the snps,dwc3.yaml
dt-binding for clock names.
Unfortunately the rk3328 (and upcoming rk356x support) use the
rockchip,dwc3.yaml which has different clock names, which are common on
devices using the glue layer.
The rk3328 does not use a glue layer, but attaches directly to the dwc3
core driver.
The offending patch series failed to account for this, thus dwc3 was
broken on rk3328.

To retain backwards compatibility with rk3328 device trees we must also
check for the alternate clock names.

Weitao Wango f085bd4bfe USB: Fix ehci infinite suspend-resume loop issue in zhaoxin
In zhaoxin platform, some ehci projects will latch a wakeup signal
internal when plug in a device on port during system S0. This wakeup
signal will turn on when ehci runtime suspend, which will trigger a
system control interrupt that will resume ehci back to D0. As no
device connect, ehci will be set to runtime suspend and turn on the
internal latched wakeup signal again. It will cause a suspend-resume
loop and generate system control interrupt continuously.

Fixed this issue by clear wakeup signal latched in ehci internal when
ehci resume callback is called.

Kees Cook e23e50e7ac USB: serial: whiteheat: fix heap overflow in WHITEHEAT_GET_DTR_RTS
The sizeof(struct whitehat_dr_info) can be 4 bytes under CONFIG_AEABI=n
due to "-mabi=apcs-gnu", even though it has a single u8:

whiteheat_private {
        __u8                       mcr;                  /*     0     1 */

        /* size: 4, cachelines: 1, members: 1 */
        /* padding: 3 */
        /* last cacheline: 4 bytes */
};

The result is technically harmless, as both the source and the
destinations are currently the same allocation size (4 bytes) and don't
use their padding, but if anything were to ever be added after the
"mcr" member in "struct whiteheat_private", it would be overwritten. The
structs both have a single u8 "mcr" member, but are 4 bytes in padded
size. The memcpy() destination was explicitly targeting the u8 member
(size 1) with the length of the whole structure (size 4), triggering
the memcpy buffer overflow warning:

Arnd Bergmann 08d3df8c81 ARM: pxa: split up mach/hardware.h
The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

The first U3 wake signal by the host may be lost if the USB 3 connection is
tunneled over USB4, with a runtime suspended USB4 host, and firmware
implemented connection manager.

Specs state the host must wait 100ms (tU3WakeupRetryDelay) before
resending a U3 wake signal if device doesn't respond, leading to U3 -> U0
link transition times around 270ms in the tunneled case.

While rebooting, XHCI controller and its bus device will be shut down
in order by .shutdown callback. Stopping roothubs polling in
xhci_shutdown() can prevent XHCI driver from accessing port status
after its bus device shutdown.

Take PCIe XHCI controller as example, if XHCI driver doesn't stop roothubs
polling, XHCI driver may access PCIe BAR register for port status after
parent PCIe root port driver is shutdown and cause PCIe bus error.

Weitao Wang e91ac20889 USB: Fix xhci event ring dequeue pointer ERDP update issue
In some situations software handles TRB events slower than adding TRBs.
If the number of TRB events to be processed in a given interrupt is exactly
the same as the event ring size 256, then the local variable
"event_ring_deq" that holds the initial dequeue position is equal to
software_dequeue after handling all 256 interrupts.

It will cause driver to not update ERDP to hardware,

Software dequeue pointer is out of sync with ERDP on interrupt exit.
On the next interrupt, the event ring may full but driver will not
update ERDP as software_dequeue is equal to ERDP.

Linus Torvalds 02e2af20f4 Char/Misc and other driver updates for 5.18-rc1
Here is the big set of char/misc and other small driver subsystem
 updates for 5.18-rc1.
 
 Included in here are merges from driver subsystems which contain:
 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers
 	- phy driver updates and new drivers
 	- coresight driver updates
 	- icc driver updates
 
 Individual changes include:
 	- mei driver updates
 	- interconnect driver updates
 	- new PECI driver subsystem added
 	- vmci driver updates
 	- lots of tiny misc/char driver updates
 
 There will be two merge conflicts with your tree, one in MAINTAINERS
 which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
 which also should be easy to resolve.
 
 All of these have been in linux-next for a while with no reported
 problems.

Linus Torvalds 710f5d627a USB/Thunderbolt patches for 5.18-rc1
Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
 
 Nothing major in here, just lots of little improvements and cleanups and
 new device support.  Highlights are:
 	- list iterator fixups for when we walk past the end of the list
 	  (a common problem that was cut/pasted in almost all USB gadget
 	  drivers)
 	- xen USB driver "hardening" for malicious hosts
 	- xhci driver updates and fixes for more hardware types
 	- xhci debug cable fixes to make it actually work again
 	- usb gadget audio driver improvements
 	- usb gadget storage fixes to work with OS-X
 	- lots of other small usb gadget fixes and updates
 	- USB DWC3 driver improvements for more hardware types
 	- Lots of other small USB driver improvements
 	- DTS updates for some USB platforms
 
 Note, the DTS updates will have a merge conflict in your tree.  The
 fixup should be simple, but if not, I can provide a merged tree if
 needed.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

Pull power management updates from Rafael Wysocki:
 "These are mostly fixes and cleanups all over the code and a new piece
  of documentation for Intel uncore frequency scaling.

  Functionality-wise, the intel_idle driver will support Sapphire Rapids
  Xeons natively now (with some extra facilities for controlling
  C-states more precisely on those systems), virtual guests will take
  the ACPI S4 hardware signature into account by default, the
  intel_pstate driver will take the defualt EPP value from the firmware,
  cpupower utility will support the AMD P-state driver added in the
  previous cycle, and there is a new tracer utility for that driver.

  Specifics:

   - Allow device_pm_check_callbacks() to be called from interrupt
     context without issues (Dmitry Baryshkov).

   - Modify devm_pm_runtime_enable() to automatically handle
     pm_runtime_dont_use_autosuspend() at driver exit time (Douglas
     Anderson).

   - Make the schedutil cpufreq governor use to_gov_attr_set() instead
     of open coding it (Kevin Hao).

   - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
     cpufreq longhaul driver (Rafael Wysocki).

   - Unify show() and store() naming in cpufreq and make it use
     __ATTR_XX (Lianjie Zhang).

   - Make the intel_pstate driver use the EPP value set by the firmware
     by default (Srinivas Pandruvada).

   - Re-order the init checks in the powernow-k8 cpufreq driver (Mario
     Limonciello).

   - Make the ACPI processor idle driver check for architectural support
     for LPI to avoid using it on x86 by mistake (Mario Limonciello).

   - Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
     Bityutskiy).

   - Add 'preferred_cstates' module argument to the intel_idle driver to
     work around C1 and C1E handling issue on Sapphire Rapids (Artem
     Bityutskiy).

   - Add core C6 optimization on Sapphire Rapids to the intel_idle
     driver (Artem Bityutskiy).

   - Optimize the haltpoll cpuidle driver a bit (Li RongQing).

   - Remove leftover text from intel_idle() kerneldoc comment and fix up
     white space in intel_idle (Rafael Wysocki).

   - Fix load_image_and_restore() error path (Ye Bin).

   - Fix typos in comments in the system wakeup hadling code (Tom Rix).

   - Clean up non-kernel-doc comments in hibernation code (Jiapeng
     Chong).

Pull ACPI updates from Rafael Wysocki:
 "From the new functionality perspective, the most significant items
  here are the new driver for the 'ARM Generic Diagnostic Dump and
  Reset' device, the extension of fine grain fan control in the ACPI fan
  driver, and the change making it possible to use CPPC information to
  obtain CPU capacity.

  There are also a few new quirks, a bunch of fixes, including the
  platform-level _OSC handling change to make it actually take the
  platform firmware response into account, some code and documentation
  cleanups, and a notable update of the ACPI device enumeration
  documentation.

Alan Stern 1892bf9067 USB: usb-storage: Fix use of bitfields for hardware data in ene_ub6250.c
The kernel test robot found a problem with the ene_ub6250 subdriver in
usb-storage: It uses structures containing bitfields to represent
hardware bits in its SD_STATUS, MS_STATUS, and SM_STATUS bytes.  This
is not safe; it presumes a particular bit ordering and it assumes the
compiler will not insert padding, neither of which is guaranteed.

This patch fixes the problem by changing the structures to simple u8
values, with the bitfields replaced by bitmask constants.

Mauro Carvalho Chehab 9958d30f38 media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

 dev_attr_show+0x4b/0x90 drivers/base/core.c:2094

Although the bug manifested in the driver core, the real cause was a
race with the gadget core.  dev_uevent() does:

	if (dev->driver)
		add_uevent_var(env, "DRIVER=%s", dev->driver->name);

and between the test and the dereference of dev->driver, the gadget
core sets dev->driver to NULL.

The race wouldn't occur if the gadget core registered its devices on
a real bus, using the standard synchronization techniques of the
driver core.  However, it's not necessary to make such a large change
in order to fix this bug; all we need to do is make sure that
udc->dev.driver is always NULL.

In fact, there is no reason for udc->dev.driver ever to be set to
anything, let alone to the value it currently gets: the address of the
gadget's driver.  After all, a gadget driver only knows how to manage
a gadget, not how to manage a UDC.

This patch simply removes the statements in the gadget core that touch
udc->dev.driver.

Thinh Nguyen e4cf6580ac usb: dwc3: gadget: Wait for ep0 xfers to complete during dequeue
If a Setup packet is received but yet to DMA out, the controller will
not process the End Transfer command of any endpoint. Polling of its
DEPCMD.CmdAct may block setting up TRB for Setup packet, causing a
command timeout.

This may occur if the driver doesn’t service the completion interrupt of
the control status stage yet due to system latency, then it won’t
prepare TRB and start the transfer for the next Setup Stage. To the host
side, the control transfer had completed, and the host can send a new
Setup packet at this point.

In the meanwhile, if the driver receives an async call to dequeue a
request (triggering End Transfer) to any endpoint, then the driver will
service that End transfer first, blocking the control status stage
completion handler. Since no TRB is available for the Setup stage, the
Setup packet can’t be DMA’ed out and the End Transfer gets hung.

The driver must not block setting up of the Setup stage. So track and
only issue the End Transfer command only when there’s Setup TRB prepared
so that the controller can DMA out the Setup packet. Delay the End
transfer command if there's no Setup TRB available. This is applicable to
all DWC_usb3x IPs.

When list_for_each_entry() completes the iteration over the whole list
without breaking the loop, the iterator value will be a bogus pointer
computed based on the head element.

While it is safe to use the pointer to determine if it was computed
based on the head element, either with list_entry_is_head() or
&pos->member == head, using the iterator variable after the loop should
be avoided.

In preparation to limiting the scope of a list iterator to the list
traversal loop, use a dedicated pointer to point to the found element [1].

Determining if an element was found is then simply checking if
the pointer is != NULL instead of using the potentially bogus pointer.

  usb: musb: Set the DT node on the child device

  The musb glue drivers just copy the glue resources to the musb child device.
  Instead, set the musb child device's DT node pointer to the parent device's
  node so that platform_get_irq_byname() can find the resources in the DT.
  This removes the need for statically populating the IRQ resources from the
  DT which has been deprecated for some time.

Thinh Nguyen aa6812be1f usb: dwc3: gadget: Give some time to schedule isoc
Currently the driver will schedule isoc transfers immediately on the
next interval, which is quite aggressive when the interval is 125us.
There's report that some platforms may need more time to process the
transfer, otherwise the controller may miss the first interval. Let's
keep it simple and give the controller at least 500us to schedule the
isoc transfer.

the internal 2.0(utmi/ulpi) clock to be routed as the 3.0 (pipe)
clock. Enabling this feature allows the pipe3 clock to be not-running

* PWR pad polarity
* controlling PPC flag in HCCPARAMS register
* permanent port attach for usb2 & usb3 port

Allow setting these flags by supporting specific flags in the glue node.
In order to get this to work an additional IORESOURCE_MEM and clock is
necessary. For backward compatibility this is purely optional.

If we try to use raw_ioctl_ep_enable() for ep5in on a hardware that

I think it will be more intuitive if we return -EINVAL, because -EBUSY
sounds like ep5in is not available now, but might be available in the

Youngjin Jang a759de6991 PM: sleep: Add device name to suspend_report_result()
Currently, suspend_report_result() prints only function information.

If any driver uses a common PM function, nobody knows who exactly
called the failing function.

A device pinter is needed to recognize the failing device.

For example:

 PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 0
 PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns 0

become after the change:

 serial 00:05: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 0
 pci 0000:00:01.3: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns 0

Juergen Gross cd7bcfab4e xen/usb: don't use gnttab_end_foreign_access() in xenhcd_gnttab_done()
The usage of gnttab_end_foreign_access() in xenhcd_gnttab_done() is
not safe against a malicious backend, as the backend could keep the
I/O page mapped and modify it even after the granted memory page is
being used for completely other purposes in the local system.

So replace that use case with gnttab_try_end_foreign_access() and
disable the PV host adapter in case the backend didn't stop using the
granted page.

In xenhcd_urb_request_done() immediately return in case of setting
the device state to "error" instead of looking into further backend
responses.

Henry Lin 70c05e4cf6 xhci: fix runtime PM imbalance in USB2 resume
A race between system resume and device-initiated resume may result in
runtime PM imbalance on USB2 root hub. If a device-initiated resume
starts and system resume xhci_bus_resume() directs U0 before hub driver
sees the resuming device in RESUME state, device-initiated resume will
not be finished in xhci_handle_usb2_port_link_resume(). In this case,
usb_hcd_end_port_resume() call is missing.

This changes calls usb_hcd_end_port_resume() if resuming device reaches
U0 to keep runtime PM balance.

xhci_decode_ctrl_ctx() returns the untouched buffer as-is if both "drop"
and "add" parameters are zero.

Fix the function to return an empty string in that case.

It was not immediately clear from the possible call chains whether this
issue is currently actually triggerable or not.

Note that before commit 4843b4b5ec ("xhci: fix even more unsafe memory
usage in xhci tracing") the result effect in the failure case was different
as a static buffer was used here, but the code still worked incorrectly.

Anssi Hannula 3105bc977d xhci: fix garbage USBSTS being logged in some cases
xhci_decode_usbsts() is expected to return a zero-terminated string by
its only caller, xhci_stop_endpoint_command_watchdog(), which directly
logs the return value:

  xhci_warn(xhci, "USBSTS:%s\n", xhci_decode_usbsts(str, usbsts));

However, if no recognized bits are set in usbsts, the function will
return without having called any sprintf() and therefore return an
untouched non-zero-terminated caller-provided buffer, causing garbage
to be output to log.

Fix that by always including the raw value in the output.

Note that before commit 4843b4b5ec ("xhci: fix even more unsafe memory
usage in xhci tracing") the result effect in the failure case was different
as a static buffer was used here, but the code still worked incorrectly.

Mathias Nyman 14073ce951 xhci: make xhci_handshake timeout for xhci_reset() adjustable
xhci_reset() timeout was increased from 250ms to 10 seconds in order to
give Renesas 720201 xHC enough time to get ready in probe.

xhci_reset() is called with interrupts disabled in other places, and
waiting for 10 seconds there is not acceptable.

Add a timeout parameter to xhci_reset(), and adjust it back to 250ms
when called from xhci_stop() or xhci_shutdown() where interrupts are
disabled, and successful reset isn't that critical.
This solves issues when deactivating host mode on platforms like SM8450.

For now don't change the timeout if xHC is reset in xhci_resume().
No issues are reported for it, and we need the reset to succeed.
Locking around that reset needs to be revisited later.

Additionally change the signed integer timeout parameter in
xhci_handshake() to a u64 to match the timeout value we pass to
readl_poll_timeout_atomic()

Christoph Hellwig ce70fd9a55 scsi: core: Remove the cmd field from struct scsi_request
Now that each scsi_request is backed by a scsi_cmnd, there is no need to
indirect the CDB storage.  Change all submitters of SCSI passthrough
requests to store the CDB information directly in the scsi_cmnd, and while
doing so allocate the full 32 bytes that cover all Linux supported SCSI
hosts instead of requiring dynamic allocation for > 16 byte CDBs.  On
64-bit systems this does not change the size of the scsi_cmnd at all, while
on 32-bit systems it slightly increases it for now, but that increase will
be made up by the removal of the remaining scsi_request fields.

Alan Stern f6a9a2d64d USB: core: Update kerneldoc for usb_get_dev() and usb_get_intf()
The kerneldoc for usb_get_dev() and usb_get_intf() says that drivers
should always refcount the references they hold for the usb_device or
usb_interface structure, respectively.  But this is an overstatement:
In many cases drivers do not access these references after they have
been unbound, and in such cases refcounting is unnecessary.

This patch updates the kerneldoc for the two routines, explaining when
a driver does not need to increment and decrement the refcount.  This
should help dispel misconceptions which might otherwise afflict
programmers new to the USB subsystem.

Pali Rohár 8e10548f7f Revert "usb: host: xhci: mvebu: make USB 3.0 PHY optional for Armada 3720"
This reverts commit 3241929b67.

Armada 3720 phy driver (phy-mvebu-a3700-comphy.c) does not return
-EOPNOTSUPP from phy_power_on() callback anymore.

So remove XHCI_SKIP_PHY_INIT flag from xhci_mvebu_a3700_plat_setup() and
then also whole xhci_mvebu_a3700_plat_setup() function which is there just
to handle -EOPNOTSUPP for XHCI_SKIP_PHY_INIT.

xhci plat_setup callback is not used by any other xhci plat driver, so
remove this callback completely.

Sebastian Andrzej Siewior 84918a89d6 usb: dwc3: gadget: Let the interrupt handler disable bottom halves.
The interrupt service routine registered for the gadget is a primary
handler which mask the interrupt source and a threaded handler which
handles the source of the interrupt. Since the threaded handler is
voluntary threaded, the IRQ-core does not disable bottom halves before
invoke the handler like it does for the forced-threaded handler.

Due to changes in networking it became visible that a network gadget's
completions handler may schedule a softirq which remains unprocessed.
The gadget's completion handler is usually invoked either in hard-IRQ or
soft-IRQ context. In this context it is enough to just raise the softirq
because the softirq itself will be handled once that context is left.
In the case of the voluntary threaded handler, there is nothing that
will process pending softirqs. Which means it remain queued until
another random interrupt (on this CPU) fires and handles it on its exit
path or another thread locks and unlocks a lock with the bh suffix.
Worst case is that the CPU goes idle and the NOHZ complains about
unhandled softirqs.

Disable bottom halves before acquiring the lock (and disabling
interrupts) and enable them after dropping the lock. This ensures that
any pending softirqs will handled right away.

BTW, the interface 0x6 of MBIM mode is GNSS port, which not same as NMEA

The remaining interfaces 0x2-0x5 are: MODEM, MODEM, NMEA, DIAG.

Hans de Goede 582ab24e09 usb: dwc3: pci: Set "linux,phy_charger_detect" property on some Bay Trail boards
Some Android x86 tablets with a Bay Trail (BYT) SoC and a Crystal Cove
PMIC, which does not support charger-detection, rely on the TUSB1211 phy
for charger-detection.

Windows tablets with the same SoC + PMIC often use an extra chip for
charger-detection like the FSA831A. But since on Android tablets
the designers already need to add a TUSB1211 phy to support device/gadget
mode the phy is used to do charger-detection instead.

These Android x86 tablets can be identified by the unique combination of
a Bay Trail SoC (already checked for by PCI-ids) + a Crystal Cove PMIC +
not using the standard ACPI battery and ac drivers. Where as on Windows
tablets the standard ACPI battery and ac drivers will be used on BYT
boards with a Crystal Cove PMIC.

Set a special kernel-internal (so not part of the dt-bindings)
"linux,phy_charger_detect" property on these boards, which tells the
tusb1210 driver to enable charger-detection.

Mathias Nyman cd36facf10 usb: remove Link Powermanagement (LPM) disable before port reset.
Trying to disable Link Powermanagement (LPM) before port reset is
unnecessary and can cause additional delay if host can't communicate
with the device, which is often the reason why device is reset in the
first place.

usb_disable_lpm() will
- zero usb U1/U2 timeouts for the hub downstream port
- send ENABLE U1/U2 clear feature requests to the connected device.
- increase internal reference count for udev->lpm_disable_count

There is no need to zero U1/U2 hub port timeouts, or clearing the
U1/U2 enable for the connected device before reset. These are set
to default by the reset.

USB 3.1 section 10.2.2 "HUB Downstream port U1/U2 timers" states that:
"the U1 and U2 timeout values for a downstream port reset to the default
values when the port receives a SetPortFeature request for a port reset"

Set the udev->lpm_disable_count to "1" after port reset, which is the
default lpm_disable_count value when allocating udev, representing
disabled LPM.

When the gadget driver hasn't been (yet) configured, and the cable is

getting lucky, some dmesg can be observed at the host side:
 new high-speed USB device number ...
 device descriptor read/64, error -110

Fix it in drd, by checking the enabled flag before calling
dwc2_hsotg_core_connect(). It will be called later, once configured,
by the normal flow:
- udc_bind_to_driver
 - usb_gadget_connect

Hans de Goede d7c93a903f usb: dwc3: pci: Add "snps,dis_u2_susphy_quirk" for Intel Bay Trail
Commit e0082698b6 ("usb: dwc3: ulpi: conditionally resume ULPI PHY")
fixed an issue where ULPI transfers would timeout if any requests where
send to the phy sometime after init, giving it enough time to auto-suspend.

Commit e5f4ca3fce ("usb: dwc3: ulpi: Fix USB2.0 HS/FS/LS PHY suspend
regression") changed the behavior to instead of clearing the
DWC3_GUSB2PHYCFG_SUSPHY bit, add an extra sleep when it is set.

But on Bay Trail devices, when phy_set_mode() gets called during init,
this leads to errors like these:
[   28.451522] tusb1210 dwc3.ulpi: error -110 writing val 0x01 to reg 0x0a
[   28.464089] tusb1210 dwc3.ulpi: error -110 writing val 0x01 to reg 0x0a

Add "snps,dis_u2_susphy_quirk" to the settings for Bay Trail devices to
fix this. This restores the old behavior for Bay Trail devices, since
previously the DWC3_GUSB2PHYCFG_SUSPHY bit would get cleared on the first
ulpi_read/_write() and then was never set again.

Ingo Rohloff 6a3cd5bef2 USB: usbfs: Use a spinlock instead of atomic accesses to tally used memory.
While the existing code code imposes a limit on the used memory, it might be
over pessimistic (even if this is unlikely).

Example scenario:
8 threads running in parallel, all entering
"usbfs_increase_memory_usage()" at the same time.
The atomic accesses in "usbfs_increase_memory_usage()" could be
serialized like this:
  8 x "atomic64_add"
  8 x "atomic64_read"
If the 8 x "atomic64_add" raise "usbfs_memory_usage" above the limit,
then all 8 calls of "usbfs_increase_memory_usage()" will return with
-ENOMEM.  If you instead serialize over the whole access to
"usbfs_memory_usage" by using a spinlock, some of these calls will
succeed.

Fabrice Gasnier 269cbcf7b7 usb: dwc2: drd: fix soft connect when gadget is unconfigured
When the gadget driver hasn't been (yet) configured, and the cable is
connected to a HOST, the SFTDISCON gets cleared unconditionally, so the
HOST tries to enumerate it.
At the host side, this can result in a stuck USB port or worse. When
getting lucky, some dmesg can be observed at the host side:
 new high-speed USB device number ...
 device descriptor read/64, error -110

Fix it in drd, by checking the enabled flag before calling
dwc2_hsotg_core_connect(). It will be called later, once configured,
by the normal flow:
- udc_bind_to_driver
 - usb_gadget_connect
   - dwc2_hsotg_pullup
     - dwc2_hsotg_core_connect

Fabio M. De Francesco c853685d11 usb: core: Unregister device on component_add() failure
Commit 8c67d06f3f ("usb: Link the ports to the connectors they are
attached to") creates a link to the USB Type-C connector for every new
port that is added when possible. If component_add() fails,
usb_hub_create_port_device() prints a warning but does not unregister
the device and does not return errors to the callers.

Syzbot reported a "WARNING in component_del()".

Fix this issue in usb_hub_create_port_device by calling device_unregister()
and returning the errors from component_add().

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Udipto Goswami 117b4e96c7 usb: dwc3: gadget: Prevent core from processing stale TRBs
With CPU re-ordering on write instructions, there might
be a chance that the HWO is set before the TRB is updated
with the new mapped buffer address.
And in the case where core is processing a list of TRBs
it is possible that it fetched the TRBs when the HWO is set
but before the buffer address is updated.
Prevent this by adding a memory barrier before the HWO
is updated to ensure that the core always process the
updated TRBs.

Sean Anderson 596c87856e usb: dwc3: Program GFLADJ
GUCTL.REFCLKPER can only account for clock frequencies with integer
periods. To address this, program REFCLK_FLADJ with the relative error
caused by period truncation. The formula given in the register reference
has been rearranged to allow calculation based on rate (instead of
period), and to allow for fixed-point arithmetic.

Additionally, calculate a value for 240MHZDECR. This configures a
simulated 240Mhz clock using a counter with one fractional bit (PLS1).

This register is programmed only for versions >= 2.50a, since this is
the check also used by commit db2be4e9e3 ("usb: dwc3: Add frame length
adjustment quirk").
