usb: dwc3: run gadget disconnect from sleepable suspend context
dwc3_gadget_suspend() takes dwc->lock with IRQs disabled and then calls
dwc3_disconnect_gadget(). For async callbacks that helper only uses
plain spin_unlock()/spin_lock(), so the gadget ->disconnect() callback
still runs with IRQs disabled and any sleepable callback trips Lockdep.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the dwc3_gadget_suspend() ->
dwc3_disconnect_gadget() -> gadget_driver->disconnect() chain, and
Lockdep reported:
BUG: sleeping function called from invalid context
gadget_disconnect+0x21/0x39 [vuln_msv]
dwc3_gadget_suspend.constprop.0+0x2b/0x42 [vuln_msv]
Keep the disconnect callback selection in one common helper, but add a
sleepable suspend-side wrapper which snapshots the callback under
dwc->lock and then runs it after spin_unlock_irqrestore(). The regular
event path still uses the existing spin_unlock()/spin_lock() window.

usb: sl811-hcd: disable controller wakeup on remove
sl811h_probe() enables the HCD controller device as a wakeup source after
usb_add_hcd() succeeds, but sl811h_remove() removes the HCD and releases
the driver resources without disabling that wakeup source.
Disable controller wakeup after usb_remove_hcd() and before usb_put_hcd()
so the wakeup source object is detached while the controller device pointer
is still available.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

usb: typec: anx7411: use devm_pm_runtime_enable()
anx7411_i2c_probe() enables runtime PM before returning successfully, but
anx7411_i2c_remove() tears down the Type-C partner state, workqueue, dummy
I2C device, mux, switch and port without disabling runtime PM.
Use devm_pm_runtime_enable() so runtime PM is disabled automatically on
driver detach. Since devres action registration can fail, route that
failure through the existing probe unwind path.

usb: dwc3: fix dwc3_readl() and dwc3_writel() calls in dwc3_ulpi_setup()
The dwc3_ulpi_setup() calls the register read and write calls with
dwc3->regs when both these calls take the dwc3 structure directly.
Chnage these two calls to fix the following sparse warning, and
possibly a nasty bug in the dwc3_ulpi_setup() code:
drivers/usb/dwc3/core.c:796:45: warning: incorrect type in argument 1 (different address spaces)
drivers/usb/dwc3/core.c:796:45: expected struct dwc3 *dwc

USB: misc: uss720: unregister parport on probe failure
uss720_probe() registers a parport before reading the 1284 register used
to detect unsupported Belkin F5U002 adapters. If get_1284_register()
fails, the error path drops the driver private data and the USB device
reference, but leaves the parport device registered.
Leaving the port registered is more than a private allocation leak:
parport_register_port() has already reserved a parport number and
registered the parport bus device, while pp->private_data still points at
the private data that the common error path is about to release.
Undo the pre-announce registration in the get_1284_register() failure
branch before jumping to the common private-data cleanup path. Clear
priv->pp first, matching the disconnect path and avoiding a stale pointer
in the private data.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

usb: free iso schedules on failed submit
EHCI and FOTG210 isochronous submits build an ehci_iso_sched before linking the URB to the endpoint queue, and keep the staged schedule in urb->hcpriv until iso_stream_schedule() and the link helpers consume it. If the controller is no longer accessible, or usb_hcd_link_urb_to_ep() fails, submit jumps to done_not_linked before that handoff happens and leaks the staged schedule still attached to urb->hcpriv. Free the staged schedule from done_not_linked when submit fails before the URB is linked and clear urb->hcpriv after the free. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1.1. An x86_64 allyesconfig build showed no new warnings. As we do not have an EHCI host controller with a USB isochronous device to test with, no runtime testing was able to be performed. Fixes: |

usb: gadget: f_printer: take kref only for successful open
printer_open() returns -EBUSY when the character device is already
open, but it increments dev->kref regardless of the return value. VFS
does not call ->release() for a failed open, so every rejected second
open permanently leaks one reference.
Move kref_get() into the successful-open branch.

usbip: vudc: fix NULL deref in vep_dequeue()
vep_alloc_request() wasn't initializing vrequest->udc, so cancellations
on the FunctionFS AIO path were arriving in vep_dequeue without a valid
UDC reference.
Since vrequest->udc is never actually properly used anywhere, we opt to
remove it, and update vep_dequeue to obtain a reference to the udc with
ep_to_vudc(), consistent with the other vep_ ops.
AFAICT this bug has existed for ~10 years. Seems that nobody has really
stressed the FunctionFS AIO path on usbip's vudc.
I tested this fix in a QEMU aarch64 guest driving FunctionFS endpoints
via AIO. Before the fix, running `usbip attach` from the host would
cause the guest to oops with the following backtrace:

usbip: tools: support SuperSpeedPlus devices
USB devices running at SuperSpeedPlus report "10000" or "20000" in
their sysfs speed attribute. usbip currently maps only "5000" to
USB_SPEED_SUPER, so a SuperSpeedPlus device is imported as
USB_SPEED_UNKNOWN.
The attach request is then rejected by vhci_hcd:
vhci_hcd: Failed attach request for unsupported USB speed: UNKNOWN
Map the SuperSpeedPlus sysfs speed values to USB_SPEED_SUPER_PLUS, use
the SuperSpeed VHCI hub for SuperSpeedPlus devices, and recognize the
gadget current_speed string used by the kernel.

usb: typec: ucsi: Pass full DP config payload in SET_NEW_CAM for DP alt mode
In the UCSI Specification Revision 3.1 RC1, bits 32-63 of the SET_NEW_CAM
command hold the 32-bit Alternate Mode Specific (AMSpecific) field.
For DisplayPort Alternate Mode, this field must contain the full
32-bit DisplayPort configuration VDO payload that the OPM wants the
connector to operate in, rather than just the pin assignment value.
This AMSpecific value follows the DisplayPort Configurations defined
in the DisplayPort Alt Mode on USB Type-C Specification v2.1a,
Table 5-13: SOP DisplayPort Configurations.

USB: serial: keyspan_pda: fix information leak
The write() callback is supposed to return the number of characters
accepted or a negative errno. Since the addition of write fifo support
the keyspan_pda implementation will however return the number characters
submitted to the device if the write urb is not already in use. If this
number is larger than the number of characters passed to write(), the
line discipline continues writing data from beyond the tty write buffer.
Fix the information leak by making sure that keyspan_pda_write_start()
returns zero on success as intended.

USB: serial: digi_acceleport: fix write buffer corruption
The digi_write_inb_command() is supposed to wait for the write urb to
become available or return an error, but instead it updates the transfer
buffer and tries to resubmit the urb on timeout.
To make things worse, for commands like break control where no timeout
is used, the driver would corrupt the urb immediately due to a broken
jiffies comparison (on 32-bit machines this takes five minutes of uptime
to trigger due to INITIAL_JIFFIES).
Fix this by adding the missing return on timeout and waiting
indefinitely when no timeout has been specified as intended.
This issue was (sort of) flagged by Sashiko when reviewing an unrelated

usb: misc: usbio: bound bulk IN response length to the received transfer
usbio_bulk_msg() copies bpkt_len = le16_to_cpu(bpkt->len) bytes out of
the bulk IN buffer (usbio->rxbuf, allocated with size usbio->rxbuf_len)
into the caller's buffer. bpkt_len is fully controlled by the device
and is only checked against ibuf_len; ibuf_len in turn is checked
against usbio->txbuf_len, not against rxbuf_len:
if ((obuf_len > (usbio->txbuf_len - sizeof(*bpkt))) ||
(ibuf_len > (usbio->txbuf_len - sizeof(*bpkt))))
return -EMSGSIZE;
txbuf_len and rxbuf_len are taken independently from the bulk OUT and
bulk IN endpoint wMaxPacketSize in usbio_probe(). A malicious or
malfunctioning device that advertises a large bulk OUT endpoint and a
small bulk IN endpoint (e.g. by claiming one of the quirk-free IDs such
as the Lattice NX33U, 0x2ac1:0x20cb) therefore makes ibuf_len, and
hence the device-supplied bpkt_len, exceed rxbuf_len. memcpy() then
reads up to txbuf_len - rxbuf_len bytes past the end of the rxbuf slab
object. The over-read bytes are handed back to the i2c layer and on to
user space through i2c-dev, disclosing adjacent slab memory; with KASAN
this is reported as a slab-out-of-bounds read.
The number of bytes actually received is already known: act equals the
URB actual_length and is bounded by rxbuf_len. Reject any response
that claims more payload than was received, mirroring the existing
"act < sizeof(*bpkt)" check just above.
The control path (usbio_ctrl_msg()) is not affected: it uses a single
buffer (ctrlbuf) for both directions, so its analogous copy can never
leave the allocation.
Found by code review. The out-of-bounds read was confirmed under
AddressSanitizer with a faithful userspace model of usbio_bulk_msg()'s
receive path (an rxbuf_len-sized buffer, the same act/ibuf_len/bpkt_len
checks and the memcpy). A USB raw-gadget + dummy_hcd reproducer is
also available.

usb: mtu3: unmap request DMA on queue failure
mtu3_gadget_queue() maps the request before checking whether
the QMU GPD ring can accept another transfer. the request is
returned with -EAGAIN before it is linked on the endpoint
request list if mtu3_prepare_transfer() fails.
Normal completion and dequeue paths unmap requests from
mtu3_req_complete(), but this error path never reaches that

usb: dwc3: meson-g12a: fix refcount leak in dwc3_meson_g12a_resume()
If dwc3_meson_g12a_resume() succeeds in calling
reset_control_reset(), an internal triggered_count reference is
acquired. If any later step fails (usb_init, phy_init,
phy_power_on, regulator_enable, or usb_post_init), the function
returns the error without rearming the reset control. This leaks
the reference and leaves the reset control in a triggered state,
causing future reset_control_reset() calls to incorrectly return
early as if already reset.
Add an error path that calls reset_control_rearm() to balance
the reference before returning the error.

usb: gadget: composite: fix dead empty check in the USB_DT_OTG handler
The OTG branch of composite_setup() falls back to the first
configuration when none is selected:
if (cdev->config)
config = cdev->config;
else
config = list_first_entry(&cdev->configs,
struct usb_configuration, list);
if (!config)
goto done;
...
memcpy(req->buf, config->descriptors[0], value);
list_first_entry() never returns NULL. On an empty list it returns
container_of() of the list head. So the "if (!config)" check is dead.
When cdev->configs is empty, config points at the head inside struct
usb_composite_dev. config->descriptors[0] reads whatever sits at that
offset. The memcpy copies up to w_length bytes of it into the response
buffer.
cdev->configs can be empty in two cases. One is a teardown race on
gadget unbind with a control transfer in flight. The other is a driver
that sets is_otg before it adds a config. A reproducer that holds
cdev->configs empty triggers a KASAN fault in this branch.
Use list_first_entry_or_null() so the existing check does its job.

usb: atm: ueagle-atm: wait for pre-firmware load in .disconnect()
ueagle-atm uses the asynchronous request_firmware_nowait() in .probe(),
but does not wait for its completion, not even in .disconnect(); so, if the
device is unplugged meanwhile, its teardown runs concurrently with that.
Even though this inconsistency is worth addressing on its own, it has also
triggered several bug reports in syzbot over the years (some auto-closed)
where the firmware sysfs fallback mechanism (CONFIG_FW_LOADER_USER_HELPER)
creates a firmware subdirectory in the device directory during its removal,
which might hit unexpected conditions in kernfs, apparently, depending at
which point the add and remove operations raced. (See links.)
The pattern is:
usb ?-?: Direct firmware load for ueagle-atm/eagle?.fw failed with error -2
usb ?-?: Falling back to sysfs fallback for: ueagle-atm/eagle?.fw
<ERROR>
Call trace:
...
kernfs_create_dir_ns
sysfs_create_dir_ns
create_dir
kobject_add_internal
kobject_add_varg
kobject_add

get_device_parent
device_add
fw_load_sysfs_fallback
fw_load_from_user_helper
firmware_fallback_sysfs
_request_firmware
request_firmware_work_func
...
(Some variations are observed, after fw_load_sysfs_fallback(), e.g., [1].)
While the kernfs side is being looked at, the ueagle-atm side can be fixed
by waiting for the pre-firmware load in the .disconnect() handler.
This change has a similar approach to previous work by Andrey Tsygunka [2]
(wait_for_completion() in .disconnect()), but it is relatively different in
design/implementation; using the Originally-by tag for credit assignment.
This has been tested with:
- synthetic reproducer to check the error path;
- USB gadget (virtual device) to check the firmware upload path;
- QEMU device emulator to check the device ID re-enumeration path;
(The latter two were written by Claude; no other code/text in this commit.)

usb: gadget: f_fs: Tie read_buffer lifetime to ffs_epfile
Currently, ffs_epfile_release unconditionally frees the endpoint's
read_buffer when a file descriptor is closed. If userspace explicitly
opens the endpoint multiple times and closes one, the read_buffer is
destroyed. This can lead to silent data loss if other file descriptors
are still actively reading from the endpoint.
By tying the lifetime of the read_buffer to the ffs_epfile structure itself
(which is destroyed when the functionfs instance is torn down in
ffs_epfiles_destroy), we eliminate the brittle dependency on open/release
calls while correctly matching the conceptual lifetime of unread data on
the hardware endpoint.

usb: gadget: f_fs: Initialize epfile->in early to fix endpoint direction checks
When parsing endpoint descriptors, ffs_data_got_descs() generates the
eps_addrmap which contains the endpoint direction. However, epfile->in
was previously only populated in ffs_func_eps_enable() which executes
upon USB host connection. As a result, early userspace ioctls like
FUNCTIONFS_DMABUF_ATTACH that run before the host connects would see
epfile->in as 0, leading to incorrect DMA directions.
By moving the initialization to ffs_epfiles_create(), epfile->in is
accurate before userspace opens the endpoint files.

usb: typec: ucsi: ccg: Fix use-after-free of ucsi on remove
The threaded IRQ handler ccg_irq_handler() calls ucsi_notify_common(),
which on a connector-change event calls ucsi_connector_change() and
schedules connector work. In ucsi_ccg_remove(), ucsi_destroy() frees
uc->ucsi (kfree) before free_irq() is called, so a handler invocation
already in flight may access the freed object after ucsi_destroy().
CPU 0 (remove) | CPU 1 (threaded IRQ)
ucsi_destroy(uc->ucsi) | ccg_irq_handler()
kfree(ucsi) // FREE | ucsi_notify_common(uc->ucsi) // USE
Move free_irq() before ucsi_destroy() in the remove path. It is kept
after ucsi_unregister(): ucsi_unregister() cancels connector work whose
handler issues GET_CONNECTOR_STATUS through ucsi_send_command_common(),
which waits for a completion that is signalled from the IRQ handler, so
the IRQ must stay active until that work has been cancelled.
The probe error path already orders free_irq() before ucsi_destroy().
This bug was found by static analysis.

usb: typec: tcpm: Validate SVID index in svdm_consume_modes()
In svdm_consume_modes(), the SVID value is read from pmdata->svids using
pmdata->svid_index as an array index without bounds validation:
paltmode->svid = pmdata->svids[pmdata->svid_index];
If pmdata->svid_index is driven beyond SVID_DISCOVERY_MAX (16), it results
in an out-of-bounds read of the pmdata->svids array. Because pd_mode_data
is embedded inside struct tcpm_port, indexing past svids reads into
adjacent fields. In particular:
- At index 16, it reads the altmodes count.
- At index 18 and beyond, it reads into altmode_desc[], which contains
partner-supplied SVDM Discovery Modes VDOs.
By injecting a chosen SVID into altmode_desc[0].vdo and driving svid_index
to 20, the partner can force paltmode->svid to be loaded with an arbitrary,
partner- chosen SVID, which is then registered via
typec_partner_register_altmode().
Fix this by validating that pmdata->svid_index is non-negative and strictly
less than pmdata->nsvids before accessing the pmdata->svids array inside
svdm_consume_modes().

usb: gadget: f_fs: initialize reset_work at allocation time
ffs_fs_kill_sb() unconditionally calls cancel_work_sync() on
ffs->reset_work when a functionfs instance is unmounted:
ffs_data_reset(ffs);
cancel_work_sync(&ffs->reset_work);
However ffs->reset_work is only ever initialized via INIT_WORK() in
ffs_func_set_alt() and ffs_func_disable(), and only on the
FFS_DEACTIVATED path. That state is reached solely by ffs_data_closed()
when the instance is mounted with the "no_disconnect" option, so for the
common case (no "no_disconnect", or mounted and unmounted without ever
being deactivated) reset_work is never initialized.
ffs_data_new() allocates the ffs_data with kzalloc_obj() and does not
initialize reset_work, and ffs_data_reset()/ffs_data_clear() do not touch
it either, so reset_work.func is left NULL. cancel_work_sync() on such a
work then trips the WARN_ON(!work->func) guard in __flush_work():

On older kernels cancel_work_sync() on a zero-initialized work struct was
a silent no-op, which hid the missing initialization.
Initialize reset_work once in ffs_data_new() so it is always valid for
the lifetime of the ffs_data, and drop the now-redundant INIT_WORK()
calls from the two deactivation paths.

usb: gadget: f_fs: Fix DMA fence leak
In ffs_dmabuf_transfer(), a ffs_dma_fence object is kmalloc'd, with the
underlying dma_fence later initialized by dma_fence_init(), which sets
its kref counter to 1. Then, dma_resv_add_fence() gets a second
reference, and a pointer to the ffs_dma_fence is passed as the
usb_request's "context" field.
The dma-resv mechanism will manage the second reference, but the first
reference is never properly released; the ffs_dmabuf_cleanup() function
decreases the reference count, but only to balance with the reference
grab in ffs_dmabuf_signal_done().
The code will then slowly leak memory as more ffs_dma_fence objects are
created without being ever freed.
Address this issue by transferring ownership of the fence to the DMA
reservation object, by calling dma_fence_put() right after
dma_resv_add_fence(). The ffs_dma_fence then gets properly discarded
after being signalled.

parameter into a new flag set and then applies it with the quirk

The mask is meant to cover the flags that can be overridden by

As a result, the module parameter can set US_FL_NO_SAME, but it

USB: quirks: add NO_LPM for the Samsung T5 EVO Portable SSD
The Samsung T5 EVO Portable SSD (04e8:6200) exhibit two forms of link instability when USB Link Power Management is enabled: 1. The units fail to initialize properly on first detection, resulting in a lockup in the drive where it must be power cycled or the kernel will not recognize the presence of the device. 2. If used for sustained operations (small amounts of continuous data are transferred to the unit) then the unit will "hiccup" after roughly 8 hours of use and will disconnect and reconnect. This has a certain probability of triggering the first issue, but also causes mount points to become invalid since the device gets issued a new letter. Signed-off-by: Erich E.

xhci: dbc: support runtime suspend while DbC is in enabled state
Allow xHC to runtime suspend if DbC is in 'enabled' state for over 15 seconds without a connect. Idea is that every time we go to 'enabled' state we make sure DbC runtime pm usage is '1' and save a timestamp. if the event loop still finds DbC in enabled state 15 seconds later then it decrease DbC runtime pm usage by calling pm_runtime_put(). Enabled state is reached either when DbC is enabled by userspace or a connected/configured DbC is disconnected. When a connect is detected we make sure DbC usage count is 1. If DbC has been in 'enabled' state for 15 seconds and DbC usage is decreased to 0 by pm_runtime_put, then the whole xHC controller may runtime suspends to PCI D3 state if no other devices are using it DbC sysfs file will show 'suspended' when xHC is suspended and will wake up and enable DbC at cable connect, or when user writes 'enable' to the file. This patch was originally part of a larger DbC series, but dropped before the series was submitted to 7.2-rc1. The series has a locking issue in commit |

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
around a WiFi device defect; use a quirk or boot-time
"pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)
- Always lift 2.5GT/s restriction in PCIe failed link retraining to
avoid clamping a link to 2.5GT/s after hot-plug changes the device
(Maciej W. Rozycki)
- Request bus reassignment when not probe-only to fix an enumeration
regression on Marvell CN106XX and possibly other DT-based systems
(Ratheesh Kannoth)
- Fix procfs race between pci_proc_init() and pci_bus_add_device()
that resulted in 'proc_dir_entry ... already registered' warnings
and pointer corruption (Krzysztof Wilczyński)
- Fix sysfs race that causes 'duplicate filename' warnings and boot
panics by converting PCI resource files to static attributes
(Krzysztof Wilczyński)
- Expose sysfs 'resourceN_resize' attributes only on platforms with
PCI mmap (Krzysztof Wilczyński)
- Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
attributes (Krzysztof Wilczyński)
- Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
mmap path to match the generic path (Krzysztof Wilczyński)
- Use kstrtobool() to parse the 'rom' attribute input to avoid the
unexpected behavior of enabling the ROM when writing '0' with no
trailing newline (Krzysztof Wilczyński)
Resource management:
- Improve resource claim logging for debuggability (Ilpo Järvinen)
- Clean up several uses of const parameters (Ilpo Järvinen)
- Check option ROM header signatures and lengths before accessing to
avoid page faults and alignment faults (Guixin Liu)
ASPM:
- Don't reconfigure ASPM when entering low-power D-state; only do it
when returning back to D0 (Carlos Bilbao)
Power management:
- During suspend, set power state to 'unknown' for all devices, not
just those with drivers (Lukas Wunner)
- Skip restoring Resizable BARs and VF Resizable BARs if device
doesn't respond to config reads, to avoid invalid array accesses
(Marco Nenciarini)
- Add pci_suspend_retains_context() so drivers can tell whether
devices retain internal state across suspend/resume, since some
platforms reset devices on suspend; use this in nvme to avoid
issues on Qcom RCs (Manivannan Sadhasivam)
Power control:
- Only to power on/off devices that actually support power control to
avoid poking at incompatible devices mentioned in DT (Manivannan
Sadhasivam)
Virtualization and resets:
- Log device readiness timeouts as errors, not warnings, because the
device is likely unusable in this case (Bjorn Helgaas)
- Wait for device readiness after soft reset (D3hot ->
D0uninitialized transition), when the device may respond with
Request Retry Status (RRS) if it needs more time to initialize
(Bjorn Helgaas)
- Drop unnecessary retries when restoring BARs because resets should
now already include all required delays (Lukas Wunner)
- Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
terminates uncleanly (Jose Ignacio Tornos Martinez)
- Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
which seem not to support it correctly (Jose Ignacio Tornos
Martinez)
Peer-to-peer DMA:
- Prevent P2PDMA as well as CPU access to non-mappable BARs, e.g.,
s390 ISM BARs (Matt Evans)
- Add Intel QAT, DSA, IAA devices to whitelist (Lukas Wunner)
Endpoint framework:
- Add endpoint controller APIs for use by function drivers to
discover auxiliary blocks like DMA engines (Koichiro Den)
- Remember DesignWare eDMA engine base/size and expose them via the
EPC aux-resource API (Koichiro Den)
- Add endpoint embedded doorbell fallback, used if MSI allocation
fails (Koichiro Den)
- Validate BAR index and remove dead BAR read in endpoint doorbell
test (Carlos Bilbao)
- Unwind MSI/MSI-X vectors if NTB initialization fails part-way
through (Koichiro Den)
- Cache sleepable pci_irq_vector() value at ISR setup to avoid
calling it from hardirq context (Koichiro Den)
- Call sleepable pci_epc_raise_irq() from a work item instead of
atomic context, e.g., when setting bits in NTB peer doorbells in
the ntb_peer_db_set() path (Koichiro Den)
- Report 0-based vNTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Prevent configfs writes to vNTB db_count and other values that are
already in use after EPC attach (Koichiro Den)
- Account for vNTB db_valid reserved slots (link event 0 and
historically skipped slot 1) so they don't appear as valid
doorbells (Koichiro Den)
- Implement vNTB .db_vector_count()/mask() for doorbells so clients
can use multiple vectors and avoid thundering herds (Koichiro Den)
- Report 0-based NTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Fix doorbell bitmask and IRQ vector handling to clear only
specified bits, use the correct vector for non-contiguous Linux IRQ
numbers, and validate incoming vectors (Koichiro Den)
- Implement NTB .db_vector_count()/mask() for doorbells so clients
can use multiple vectors (Koichiro Den)
Native PCIe controller infrastructure:
- Add pci_host_common_link_train_delay() for the mandatory delay
after > 5GT/s Link training completes and use it for cadence HPA,
j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)
- Protect root bus removal with rescan lock in altera, brcmstb,
cadence, dwc, iproc, mediatek, plda, rockchip to prevent
use-after-free or crashes when racing with sysfs rescan or hotplug
(Hans Zhang)
- Add pci_host_common_parse_ports() for use by any native driver to
parse Root Port properties (per-Link features like width, speed,
PHY, power and reset control, etc should be described in Root Port
stanzas, not the host bridge; currently only reset GPIOs
implemented) (Sherry Sun)
New native PCIe controller drivers:
- Add DT binding and driver for UltraRISC DP1000 PCIe controller
(Xincheng Zhang, Jia Wang)

- Assert PERST# on shutdown so any connected Endpoints are held in
reset during shutdown (Sai Krishna Musham)

- Propagate devm_add_action_or_reset() failure to fix probe error
path (Shuvam Pandey)
- Add .remove() callback to deinitialize the host bridge and power
off the PHY (Shuvam Pandey)
Broadcom iProc PCIe controller driver:
- Restore .map_irq() assignment; its removal broke INTx on the iproc
platform bus driver (Mark Tomlinson)
Broadcom STB PCIe controller driver:
- No change, but products using certain WiFi devices may be affected
by removal of CONFIG_PCIE_BUS_* (see above)
Freescale i.MX6 PCIe controller driver:
- Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset
functions (Richard Zhu)
- Assert PERST# before enabling regulators to ensure that even if
power is enabled, endpoint stays inactive until REFCLK is stable
(Sherry Sun)
- Parse reset properties in Root Port nodes (falling back to host
bridge) to help support Key E connectors and the pwrctrl framework
(Sherry Sun)
- Configure i.MX95 REF_USE_PAD before PHY reset (Richard Zhu)
- Assert i.MX95 ref_clk_en after reference clock stabilizes (Richard
Zhu)
- Integrate new pwrctrl API for DTs with Root Port-level power
supplies (Sherry Sun)
Intel Gateway PCIe controller driver:
- Enable clock before PHY init for correct ordering (Florian Eckert)
- Add .start_link() callback so the driver works again (Florian
Eckert)
- Stop overwriting the ATU base address discovered by
dw_pcie_get_resources() (Florian Eckert)
- Add DT 'atu' region since this is hardware-specific, and fall back
to driver default if lacking (Florian Eckert)
Loongson PCIe controller driver:
- Ignore downstream devices only on internal bridges to avoid
Loongson hardware issue (Rong Zhang)
- Quirk old Loongson-3C6000 bridges that advertise incorrect

virt_to_phys() (Manivannan Sadhasivam)
- Add EcoNet EN7528 to DT binding (Caleb James DeLisle)
MediaTek PCIe Gen3 controller driver:
- Deassert PCIE_PHY_RSTB so REFCLK is stable for at least 100ms
(PCIE_T_PVPERL_MS) before deasserting PERST# (Jian Yang)
- Add .shutdown() to assert PERST# before powering down device (Jian
Yang)
- Do full device power down on removal, including asserting PERST#,
when removing driver (Chen-Yu Tsai)
- Fix a 'failed to create pwrctrl devices' error message that was
inadvertently skipped (Chen-Yu Tsai)
NVIDIA Tegra194 PCIe controller driver:
- Program the DesignWare PORT_AFR L1 entrance latency based on the
'aspm-l1-entry-delay-ns' DT property (Manikanta Maddireddy)
Qualcomm PCIe controller driver:
- Add Eliza SoC compatible in DT binding (Krishna Chaitanya Chundru)
- Set max OPP during resume so DBI register accesses don't fail with
NoC errors (Qiang Yu)

downstream devices are already in D3hot and wakeup-enabled devices
are capable of generating PME from D3cold (Krishna Chaitanya
Chundru)
- Add .get_ltssm() callback to get the LTSSM status without DBI,
since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya
Chundru)
- Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to
avoid power leakage (Krishna Chaitanya Chundru)
- Decide whether suspend should put the link in L2 and power down
using pci_host_common_d3cold_possible() instead of checking whether
ASPM L1 is enabled (Krishna Chaitanya Chundru)
- Add qcom D3cold support to tear down interconnect bandwidth and OPP
votes (Krishna Chaitanya Chundru)
- Handle unsupported mixed PERST#/PHY DT configurations, e.g., PHY in
RP node while PERST# is in the RC node, but warn about the DT issue
(Qiang Yu)
- Program T_POWER_ON based on DT 't-power-on-us' property in case
hardware advertises incorrect values (Krishna Chaitanya Chundru)
- Disable ASPM L0s for SA8775P (Shawn Guo)
- Initialize DWC MSI lock for firmware-managed ECAM hosts, which
don't use the dw_pcie_host_init() path that initializes the lock
(Yadu M G)
Renesas RZ/G3S PCIe controller driver:
- Add RZ/V2N DT support (Lad Prabhakar)
SOPHGO PCIe controller driver:
- Add 'dma-coherent' DT property for sg2042-pcie driver (Han Gao)
