Add support for ADAQ7767/68/69-1 series, which includes PGIA and
Anti-aliasing filter (AAF) gains. Unlike the AD7768-1, they do not
provide a VCM regulator interface.
The PGA gain is configured in run-time through the scale attribute,
if supported by the device. PGA is controlled by GPIOs provided in
the device tree.
The AAF gain is defined by hardware connections and should be specified
in the device tree.

Add guard classes for iio_device_claim_*() conditional locks. This will
aid drivers write safer and cleaner code when dealing with some common
patterns.
These classes are not meant to be used directly by drivers (hence the
__priv__ prefix). Instead, documented wrapper macros are provided to
enforce the use of ACQUIRE() or guard() semantics and avoid the
problematic scoped guard.

Implement iio_device_claim_buffer_mode() fully inline with the use of
__iio_dev_mode_lock(), which takes care of sparse annotations.
To completely match iio_device_claim_direct() semantics, we need to
also change iio_device_claim_buffer_mode() return semantics to usual
true/false conditional lock semantics.
Additionally, to avoid silently breaking out-of-tree drivers, rename
iio_device_claim_buffer_mode() to iio_device_claim_try_buffer_mode().

The debug messages added by commit f7599be2bb76 ("ACPI: PM: postpone
bringing devices to D0 unless we need them") in acpi_subsys_resume_early()
and acpi_subsys_resume() are not quite accurate because what is postponed
is not just a transition to D0, but also an adjustment of the device's
wakeup setting (which may involve disabling a GPE among other things).
Moreover, these messages don't even mention ACPI.
Rephrase them and adjust the style to match other messages in device_pm.c.

Previously, it was possible for a PCI device to be runtime-suspended before
it was fully initialized. When that happened, the suspend process could
save invalid device state, for example, before BAR assignment. Restoring
the invalid state during resume may leave the device non-functional.
Prevent runtime suspend for PCI devices until they are fully initialized by
deferring pm_runtime_enable().
More details on how exactly this may occur:
1. PCI device is created by pci_scan_slot() or similar
2. As part of pci_scan_slot(), pci_pm_init() puts the device in D0 and
prevents runtime suspend prevented via pm_runtime_forbid()
3. pci_device_add() adds the underlying 'struct device' via device_add(),
which means user space can allow runtime suspend, e.g.,
echo auto > /sys/bus/pci/devices/.../power/control
4. PCI device receives BAR configuration
(pci_assign_unassigned_bus_resources(), etc.)
5. pci_bus_add_device() applies final fixups, saves device state, and
tries to attach a driver
The device may potentially be suspended between #3 and #5, so this is racy
with user space (udev or similar).
Many PCI devices are enumerated at subsys_initcall time and so will not
race with user space, but devices created later by hotplug or modular
pwrctrl or host controller drivers are susceptible to this race.
More runtime PM details at the first Link: below.

Fix memory leak in set_ssp_complete() where mgmt_pending_cmd structures
are not freed after being removed from the pending list.
Commit 302a1f674c00 ("Bluetooth: MGMT: Fix possible UAFs") replaced
mgmt_pending_foreach() calls with individual command handling but missed
adding mgmt_pending_free() calls in both error and success paths of
set_ssp_complete(). Other completion functions like set_le_complete()
were fixed correctly in the same commit.
This causes a memory leak of the mgmt_pending_cmd structure and its
associated parameter data for each SSP command that completes.
Add the missing mgmt_pending_free(cmd) calls in both code paths to fix
the memory leak. Also fix the same issue in set_advertising_complete().

Add device tree for the Anbernic RG-DS, based on the Rockchip RK3568.
All hardware is currently working except for the accelerometer, the
speaker output, and one of the two battery gauges. A bug in the
Rockchip VOP2 driver is currently causing the device to pause for 30
seconds at boot and is being investigated.
The Anbernic RG-DS includes the following (supported) hardware:
- 2 640x480 DSI display screens with touch.
- 21 buttons.
- 2 Analog joysticks.
- 3 LEDs (red and green LED share the same housing).
- 32GB eMMC, 1 SDMMC slot.
- RTL8821CS WiFi/Bluetooth combo
- 1 USB 2.0 port in host mode, 1 USB 2.0 port in peripheral mode.
- 3.5mm headphone jack with play button support.
- 4000mAH battery
The following hardware has incomplete driver support and is not yet
working:
- An Invensense icm42607p accelerometer.
- Two Awinic aw87391 speaker amplifiers.
- A Cellwise cw2015 battery monitor, which appears to conflict with
the rk817 charger driver at the moment.

hci_uart_set_proto() sets HCI_UART_PROTO_INIT before calling
hci_uart_register_dev(), which calls proto->open() to initialize
hu->priv. However, if a TTY write wakeup occurs during this window,
hci_uart_tx_wakeup() may schedule write_work before hu->priv is
initialized, leading to a NULL pointer dereference in
hci_uart_write_work() when proto->dequeue() accesses hu->priv.
The race condition is:
CPU0 CPU1
---- ----
hci_uart_set_proto()
set_bit(HCI_UART_PROTO_INIT)
hci_uart_register_dev()
tty write wakeup
hci_uart_tty_wakeup()
hci_uart_tx_wakeup()
schedule_work(&hu->write_work)
proto->open(hu)
// initializes hu->priv
hci_uart_write_work()
hci_uart_dequeue()
proto->dequeue(hu)
// accesses hu->priv (NULL!)
Fix this by moving set_bit(HCI_UART_PROTO_INIT) after proto->open()
succeeds, ensuring hu->priv is initialized before any work can be
scheduled.

Rockchip RK3576 UFS controller uses a dedicated pin to reset the connected
UFS device, which can operate either in a hardware controlled mode or as a
GPIO pin.
Power-on default is GPIO mode, but the boot ROM reconfigures it to a
hardware controlled mode if it uses UFS to load the next boot stage.
Given that existing bindings (and rk3576.dtsi) expect a GPIO-controlled
device reset, request the required pin config explicitly.
The pin is requested with pull-down enabled, which is in line with the
SoC power-on default and helps ensure that the attached UFS chip stays
in reset until the driver takes over the control of the respective
GPIO line.
This doesn't appear to affect Linux, but it does affect U-boot:
Before:

2604b398: 00000011 00000000 00000000 00000000 ................
After:

2604b398: 00000011 00000000 00000000 00000000 ................
< ... snip ...>
=> ufs init
ufshcd-rockchip ufshc@2a2d0000: [RX, TX]: gear=[3, 3], lane[2, 2], pwr[FASTAUTO_MODE, FASTAUTO_MODE], rate = 2

2604b398: 00000010 00000000 00000000 00000000 ................
(0x2604b398 is the respective pin mux register, with its BIT0 driving the
mode of UFS_RST: unset = GPIO, set = hardware controlled UFS_RST)
This helps ensure that GPIO-driven device reset actually fires when the
system requests it, not when whatever black box magic inside the UFSHC
decides to reset the flash chip.

1) The commit:
2b8272ff4a70 ("cpu/hotplug: Prevent self deadlock on CPU hot-unplug")
was added to fix an issue where the hotplug control task (BP) was
throttled between CPUHP_AP_IDLE_DEAD and CPUHP_HRTIMERS_PREPARE waiting
in the hrtimer blindspot for the bandwidth callback queued in the dead
CPU.
2) Later on, the commit:
38685e2a0476 ("cpu/hotplug: Don't offline the last non-isolated CPU")
plugged on the target selection for the workqueue offloaded CPU down
process to prevent from destroying the last CPU domain.
3) Finally:
5c0930ccaad5 ("hrtimers: Push pending hrtimers away from outgoing CPU earlier")
removed entirely the conditions for the race exposed and partially fixed
in 1). The offloading of the CPU down process to a workqueue on another
CPU then becomes unnecessary. But the last CPU belonging to scheduler
domains must still remain online.
Therefore revert the now obsolete commit
2b8272ff4a70b866106ae13c36be7ecbef5d5da2 and move the housekeeping check
under the cpu_hotplug_lock write held. Since HK_TYPE_DOMAIN will include
both isolcpus and cpuset isolated partition, the hotplug lock will
synchronize against concurrent cpuset partition updates.

HK_TYPE_DOMAIN will soon integrate cpuset isolated partitions and
therefore be made modifiable at runtime. Synchronize against the cpumask
update using RCU.
The RCU locked section includes both the housekeeping CPU target
election for the PCI probe work and the work enqueue.
This way the housekeeping update side will simply need to flush the
pending related works after updating the housekeeping mask in order to
make sure that no PCI work ever executes on an isolated CPU. This part
will be handled in a subsequent patch.

This reverts commit bc6d54ac7e7436721a19443265f971f890c13cc5.
The workload profile needs to be in the default state when
the dc idle optimizaion state is entered. However, when
jobs come in for video or GFX or compute, the profile may
be set to a non-default profile resulting in the dc idle
optimizations not taking affect and resulting in higher
power usage. As such we need to pause the workload profile
changes during this transition. When this patch was originally
committed, it caused a regression with a Dell U3224KB display,
but no other problems were reported at the time. When it
was reapplied (this patch) to address increased power usage, it
seems to have caused additional regressions. This change seems
to have a number of side affects (audio issues, stuttering,
etc.). I suspect the pause should only happen when all displays
are off or in static screen mode, but I think this call site
gets called more often than that which results in idle state
entry more often than intended. For now revert.

The commit 337b1b566db0 ("PCI: Fix restoring BARs on BAR resize rollback
path") changed BAR resize to layer rebar code and resource setup/restore
code cleanly. Unfortunately, it did not consider how the value of the BAR
Size field impacts the read-only bits in the Base Address Register (PCIe7
spec, sec. 7.8.6.3). That is, it very much matters in which order the BAR
Size and Base Address Register are restored.
Post-337b1b566db0 ("PCI: Fix restoring BARs on BAR resize rollback path")
during BAR resize rollback, pci_do_resource_release_and_resize() attempts
to restore the old address to the BAR that was resized, but it can fail to
setup the address correctly if the address has low bits set that collide
with the bits that are still read-only. As a result, kernel's resource and
BAR will be out-of-sync.
Fix this by restoring BAR Size before rolling back the resource changes and
restoring the BAR.

The commit 337b1b566db0 ("PCI: Fix restoring BARs on BAR resize rollback
path") added BAR rollback to pci_do_resource_release_and_resize() in case
of resize failure.
On the rollback, pci_claim_resource() is called, which can fail and the
code is prepared for that possibility. pci_claim_resource()'s return value,
however, overwrites the original value of ret so
pci_do_resource_release_and_resize() will return an incorrect value in the
end (as pci_claim_resource() normally succeeds, in practice ret will be 0).
Fix the issue by directly calling pci_claim_resource() inside the if ().

The rbtree can temporarily store overlapping inactive elements during
the transaction processing, leading to false negative lookups.
To address this issue, this patch adds a .commit function that walks the
the rbtree to build a array of intervals of ordered elements. This
conversion compacts the two singleton elements that represent the start
and the end of the interval into a single interval object for space
efficient.
Binary search is O(log n), similar to rbtree lookup time, therefore,
performance number should be similar, and there is an implementation
available under lib/bsearch.c and include/linux/bsearch.h that is used
for this purpose.
This slightly increases memory consumption for this new array that
stores pointers to the start and the end of the interval.
With this patch:
# time nft -f 100k-intervals-set.nft
real 0m4.218s
user 0m3.544s
sys 0m0.400s
Without this patch:
# time nft -f 100k-intervals-set.nft
real 0m3.920s
user 0m3.547s
sys 0m0.276s
With this patch, with IPv4 intervals:
baseline rbtree (match on first field only): 15254954pps
Without this patch:
baseline rbtree (match on first field only): 10256119pps
This provides a ~50% improvement in matching intervals from packet path.

The pipapo set backend is the only user of the .abort interface so far.
To speed up pipapo abort path, removals are skipped.
The follow up patch updates the rbtree to use to build an array of
ordered elements, then use binary search. This needs a new .abort
interface but, unlike pipapo, it also need to undo/remove elements.
Add a flag and use it from the pipapo set backend.

Modify the internal registration helpers dpll_xa_ref_{dpll,pin}_add()
to reject duplicate registration attempts.
Previously, if a caller attempted to register the same pin multiple
times (with the same ops, priv, and cookie) on the same device, the core
silently increments the reference count and return success. This behavior
is incorrect because if the caller makes these duplicate registrations
then for the first one dpll_pin_registration is allocated and for others
the associated dpll_pin_ref.refcount is incremented. During the first
unregistration the associated dpll_pin_registration is freed and for
others WARN is fired.
Fix this by updating the logic to return `-EEXIST` if a matching
registration is found to enforce a strict "register once" policy.

- Move `sync_decompress` to sbi to avoid unexpected remount impact;
- Fold z_erofs_is_sync_decompress() into its caller;
