Updates to the usual drivers (ufs, megaraid_sas, lpfc, target, ibmvfc,
scsi_debug) plus the usual assorted minor fixes and updates. The
major change this time around is a prep patch for rethreading of the
driver reset handler API not to take a scsi_cmd structure which starts
to reduce various drivers' dependence on scsi_cmd in error handling.

In some cases, like with multiple LUN targets or where the target has to
respond to transport level requests from the receiving context it can be
better to defer cmd submission to a helper thread. If the backend driver
blocks on something like request/tag allocation it can block the entire
target submission path and other LUs and transport IO on that session.
In other cases like single LUN targets with storage that can support all
the commands that the target can queue, then it's best to submit the cmd
to the backend from the target's cmd receiving context.
Subsequent commits will allow the user to config what they prefer, but
drivers like loop can't directly submit because they can be called from a
context that can't sleep. And, drivers like vhost-scsi can support direct
submission, but need to keep their default behavior of deferring execution
to avoid possible regressions where the backend can block.
Make the drivers tell LIO core if they support direct submissions and their
current default, so we can prevent users from misconfiguring the system and
initialize devices correctly.

In some implementations, such as the Qualcomm platforms, the display
driver has no way to query the current HPD state and as such it's
impossible to distinguish between disconnect and attention events.
Add a parameter to drm_connector_oob_hotplug_event() to pass the HPD
state.
Also push the test for unchanged state in the displayport altmode driver
into the i915 driver, to allow other drivers to act upon each update.

On some OEM systems, adding a W7900 dGPU triggers RAS errors and hangs
at a black screen on startup. This issue occurs only if `ucsi_acpi` has
loaded before `amdgpu` has loaded. The reason for this failure is that
`amdgpu` uses power_supply_is_system_supplied() to determine if running
on AC or DC power at startup. If this value is reported incorrectly the
dGPU will also be programmed incorrectly and trigger errors.
power_supply_is_system_supplied() reports the wrong value because UCSI
power supplies provided as part of the system don't properly report the
scope as "DEVICE" scope (not powering the system).
In order to fix this issue check the capabilities reported from the UCSI
power supply to ensure that it supports charging a battery and that it can
be powered by AC. Mark the scope accordingly.

Upon receiving an ACK for a sent EXIT_MODE message, the DisplayPort
driver currently resets the status and configuration of the port partner.
The hpd signal is not updated despite being part of the status, so the
Display stack can still transmit video despite typec_altmode_exit placing
the lanes in a Safe State.
Set hpd to low when a sent EXIT_MODE message is ACK'ed.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct f_midi.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

The Event Handler Busy bit shall be cleared by software when the Event
Ring is empty. The xHC is thereby informed that it may raise another
interrupt once it has enqueued new events (sec 4.17.2).
However since commit dc0ffbea5729 ("usb: host: xhci: update event ring
dequeue pointer on purpose"), the EHB bit is already cleared after half
a segment has been processed.
As a result, spurious interrupts may occur:
- xhci_irq() processes half a segment, clears EHB, continues processing
remaining events.
- xHC enqueues new events. Because EHB has been cleared, xHC sets
Interrupt Pending bit. Interrupt moderation countdown begins.
- Meanwhile xhci_irq() continues processing events. Interrupt
moderation countdown reaches zero, so an MSI interrupt is signaled.
- xhci_irq() empties the Event Ring, clears EHB again and is done.
- Because an MSI interrupt has been signaled, xhci_irq() is run again.
It discovers there's nothing to do and returns IRQ_NONE.
Avoid by clearing the EHB bit only at the end of xhci_irq().

xhci-hub.c tracks suspended ports in a suspended_port bitfield.
This is checked when responding to a Get_Status(PORT) request to see if a
port in running U0 state was recently resumed, and adds the required
USB_PORT_STAT_C_SUSPEND change bit in those cases.
The suspended_port bit was left uncleared if a device is disconnected
during suspend. The bit remained set even when a new device was connected
and enumerated. The set bit resulted in a incorrect Get_Status(PORT)
response with a bogus USB_PORT_STAT_C_SUSPEND change
bit set once the new device reached U0 link state.
USB_PORT_STAT_C_SUSPEND change bit is only used for USB2 ports, but
xhci-hub keeps track of both USB2 and USB3 suspended ports.

When there's phy initialization, we need to initiate a soft-reset
sequence. That's done through USBCMD.HCRST in the xHCI driver and its
initialization, However, the dwc3 driver may modify core configs before
the soft-reset. This may result in some connection instability. So,
ensure the phy is ready before the controller updates the GCTL.PRTCAPDIR
or other settings by issuing phy soft-reset.
Note that some host-mode configurations may not expose device registers
to initiate the controller soft-reset (via DCTL.CoreSftRst). So we reset
through GUSB3PIPECTL and GUSB2PHYCFG instead.

Merge tag 'v6.6-vfs.ctime' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs timestamp updates from Christian Brauner:
"This adds VFS support for multi-grain timestamps and converts tmpfs,
xfs, ext4, and btrfs to use them. This carries acks from all relevant
filesystems.
The VFS always uses coarse-grained timestamps when updating the ctime
and mtime after a change. This has the benefit of allowing filesystems
to optimize away a lot of metadata updates, down to around 1 per
jiffy, even when a file is under heavy writes.
Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide to invalidate the cache.
Even with NFSv4, a lot of exported filesystems don't properly support
a change attribute and are subject to the same problems with timestamp
granularity. Other applications have similar issues with timestamps
(e.g., backup applications).
If we were to always use fine-grained timestamps, that would improve
the situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.
This introduces fine-grained timestamps that are used when they are
actively queried.
This uses the 31st bit of the ctime tv_nsec field to indicate that
something has queried the inode for the mtime or ctime. When this flag
is set, on the next mtime or ctime update, the kernel will fetch a
fine-grained timestamp instead of the usual coarse-grained one.
As POSIX generally mandates that when the mtime changes, the ctime
must also change the kernel always stores normalized ctime values, so
only the first 30 bits of the tv_nsec field are ever used.
Filesytems can opt into this behavior by setting the FS_MGTIME flag in
the fstype. Filesystems that don't set this flag will continue to use
coarse-grained timestamps.
Various preparatory changes, fixes and cleanups are included:
- Fixup all relevant places where POSIX requires updating ctime
together with mtime. This is a wide-range of places and all
maintainers provided necessary Acks.
- Add new accessors for inode->i_ctime directly and change all
callers to rely on them. Plain accesses to inode->i_ctime are now
gone and it is accordingly rename to inode->__i_ctime and commented
as requiring accessors.
- Extend generic_fillattr() to pass in a request mask mirroring in a
sense the statx() uapi. This allows callers to pass in a request
mask to only get a subset of attributes filled in.
- Rework timestamp updates so it's possible to drop the @now
parameter the update_time() inode operation and associated helpers.
- Add inode_update_timestamps() and convert all filesystems to it
removing a bunch of open-coding"

* tag 'usb-serial-6.6-rc1' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial:
USB: serial: option: add FOXCONN T99W368/T99W373 product
USB: serial: option: add Quectel EM05G variant (0x030e)
USB: serial: xr: add TIOCGRS485 and TIOCSRS485 ioctls
The try_src_count and try_snk_count may still be 1 after enter into
unattached state. This may be caused by below case:
- SNK_TRY->SNK_TRY_WAIT->SRC_TRYWAIT->SNK_UNATTACHED
- SRC_TRY->SRC_TRY_WAIT->SNK_TRYWAIT->SNK_UNATTACHED
The port->attached is not true at the end and tcpm_reset_port() will not
be called. This will reset counter into for these cases, otherwise the tcpm
won't try role when new cable attached.

When sending Discover Identity messages to a Port Partner that uses Power
Delivery v2 and SVDM v1, we currently send PD v2 messages with SVDM v2.0,
expecting the port partner to respond with its highest supported SVDM
version as stated in Section 6.4.4.2.3 in the Power Delivery v3
specification. However, sending SVDM v2 to some Power Delivery v2 port
partners results in a NAK whereas sending SVDM v1 does not.
NAK messages can be handled by the initiator (PD v3 section 6.4.4.2.5.1),
and one solution could be to resend Discover Identity on a lower SVDM
version if possible. But, Section 6.4.4.3 of PD v2 states that "A NAK
response Should be taken as an indication not to retry that particular
Command."
Instead, we can set the SVDM version to the maximum one supported by the
negotiated PD revision. When operating in PD v2, this obeys Section
6.4.4.2.3, which states the SVDM field "Shall be set to zero to indicate
Version 1.0." In PD v3, the SVDM field "Shall be set to 01b to indicate
Version 2.0."

The dwc2 driver has everything we need to run in PCI mode except
for pci_device_id driver_data parse. With that to set Loongson
dwc2 element and added identified as PCI_VENDOR_ID_LOONGSON
and PCI_DEVICE_ID_LOONGSON_DWC2 in dwc2_pci_ids, the Loongson
dwc2 controller will work.

Take ecm_bind() for example, it call gadget_is_{*}speed() API to show
gadget max support speed, it is not much help, remove the API usage here
is safe.
Similar change apply to acm,eem,loopback,ncm,obex,rndis,serial,
sourcesink,subset functions.
