Akashdeep Kaur 104cd764a0 mfd: tps65219: Make poweroff handler conditional on system-power-controller
Currently, the TPS65219 driver unconditionally registers a poweroff
handler. This causes issues on systems where a different component
(such as TF-A firmware) should handle system poweroff instead.

Make the poweroff handler registration conditional based on the
"system-power-controller" device tree property. This follows the
standard kernel pattern where only the designated power controller
registers for system poweroff operations.

On systems where the property is absent, the PMIC will not register
a poweroff handler, allowing other poweroff mechanisms to function.

Matthias Fend d43f1d7929 leds: tps6131x: Increase overvoltage protection threshold to 6V
Currently, there may be cases where the overvoltage detection is triggered
even with a valid and generally functioning hardware setup. This occurs,
for example, when the input voltage exceeds the currently used overvoltage
threshold of 4.65V (typical). Since input voltages up to 5V are supported,
the threshold should be adjusted accordingly.

While the target output voltage setting has no effect on the LED operation
used here, it indirectly selects the threshold for overvoltage detection.
Set this to a value of 4.95V to select a threshold of 6V (typical).

Wenyuan Li f5f40b8281 mfd: tps65910: Add error handling for dummy I2C transfer in probe
In tps65910_i2c_probe(), a dummy I2C transfer is performed to work
around silicon erratum SWCZ010. However, the return value of
i2c_master_send() is not checked.

If this dummy transfer fails, the driver continues execution without
detecting the error. This may lead to subsequent I2C operations also
failing, but the driver would incorrectly report success.

Add proper return value checking for the dummy I2C transfer. If the
transfer fails, log the error and return an appropriate error code
to the caller.

Uwe Kleine-König (The Capable Hub) a031b5fce5 leds: Use named initializers for arrays of i2c_device_data
While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace and commas.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

			   (brightness & 0xfff));
	ret = spi_write(led->spi, (const u8 *)&word, sizeof(word));

cpu_to_le16() returns __le16, but the local 'word' is declared as
plain u16, which sparse flags:

  drivers/leds/leds-dac124s085.c:42:14: warning: incorrect type in
  assignment (different base types)

The bytes that hit the wire are correct because cpu_to_le16() does
the right thing on either endianness, but mixing the annotated and
unannotated types defeats sparse's __bitwise checking and would let
a future reader treat the buffer as a host-endian u16 by mistake.

Declare 'word' as __le16 to match how it is built and consumed.

No functional change.

Armin Wolf 2682d63086 leds: Introduce the multi_max_intensity sysfs attribute
Some multicolor LEDs support global brightness control in hardware,
meaning that the maximum intensity of the color components is not
connected to the maximum global brightness. Such LEDs cannot be
described properly by the current multicolor LED class interface,
because it assumes that the maximum intensity of each color component
is described by the maximum global brightness of the LED.

Fix this by introducing a new sysfs attribute called
"multi_max_intensity" holding the maximum intensity values for the
color components of a multicolor LED class device. Drivers can use
the new max_intensity field inside struct mc_subled to tell the
multicolor LED class code about those values. Intensity values written
by userspace applications will be limited to this maximum value.

Drivers for multicolor LEDs that do not support global brightness
control in hardware might still want to use the maximum global LED
brightness supplied via devicetree as the maximum intensity of each
individual color component. Such drivers should set max_intensity
to 0 so that the multicolor LED core can act accordingly.

The lp50xx and ncp5623 LED drivers already use hardware-based control
for the global LED brightness. Modify those drivers to correctly
initalize .max_intensity to avoid being limited to the maximum global
brightness supplied via devicetree.

  X001: CONFIG_LEDS_AS3668 referenced in Makefile but not defined

The AS3668 LED driver was introduced in
commit c7dd343a37 ("leds:
as3668: Driver for the ams Osram 4-channel i2c LED driver").
That commit defined the Kconfig symbol as LEDS_OSRAM_AMS_AS3668 in
drivers/leds/Kconfig but used the shorter name LEDS_AS3668 in the
Makefile's obj-* line.

Because the Makefile references CONFIG_LEDS_AS3668 which does not exist,
the driver can never be built — the obj-* line always evaluates to
obj- += leds-as3668.o (empty config), so the object file is never
compiled regardless of what the user selects in menuconfig.

Fix the Makefile to reference the correct Kconfig symbol
CONFIG_LEDS_OSRAM_AMS_AS3668, matching what is defined in
drivers/leds/Kconfig.

Piotr Kubik 26e15f2558 leds: trigger: gpio: Use GPIOD_FLAGS_BIT_NONEXCLUSIVE
When a GPIO is shared between the LED trigger driver and another driver,
the LED trigger driver needs to request the GPIO with
GPIOD_FLAGS_BIT_NONEXCLUSIVE to allow both drivers to monitor the same
GPIO pin.

Without this flag, if another driver has already claimed the GPIO,
the LED trigger driver's gpiod_get_optional() call fails silently,
and the LED trigger doesn't work.

This is needed for scenarios like:
- SFP module presence/status LED triggered by SFP Mod_ABS/Rx_LOS

Both GPIOs are also monitored by the SFP driver for module state
management, so they need to be shared.

 echo 255 > /sys/class/leds/led-1/brightness  # blinking stops, light on
 cat /sys/class/leds/led-1/trigger            # still claims [timer]

According to Documentation/leds/leds-class.rst, only brightness = 0
shall be a stop condition:

> You can change the brightness value of a LED independently of the
> timer trigger. However, if you set the brightness value to LED_OFF it
> will also disable the timer trigger.

Therefore add a guard to continue blinking when brightness != LED_OFF,
similar to how pca955x does it since 575f10dc64 ("leds: pca955x: Add
HW blink support").

Kernel logs are filled with "DMA mask not set" messages for every
sub-device. The device does not use DMA for communication, so these
messages are useless. Disable the coherent DMA mask for the PMIC device,
which is also propagated to sub-devices.

Kaustabh Chakraborty e491ebea15 mfd: sec: Add support for S2MU005 PMIC
Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro
USB Interface Controller), and flash and RGB LED controllers.

S2MU005's interrupt registers divided into three domains, each for the
charger, flash LEDs, and the MUIC, packed into a single regmap IRQ chip
construct.

In devices other than S2MPG1X, the revision can be retrieved from the
first register of the PMIC regmap. In S2MU005 however, the location is
in offset 0x73. Introduce a switch-case block to allow selecting the
REG_ID register. S2MU005 also has a field mask for the revision. Apply
it using FIELD_GET() and get the extracted value.

Add initial support for S2MU005 in the PMIC driver, along with its three
interrupt chips, and support for allowing to fetch revision based on the
device variant.

due to AF_UNSPEC selector with large prefixlen (e.g. 128) matched
against IPv4 flow (when XFRM_STATE_AF_UNSPEC is set).

Fix this by:

Herbert Xu ddd3d01329 xfrm: Fix xfrm state cache insertion race
The xfrm input state cache insertion code checks the validity of
the state before acquiring the global xfrm_state_lock.  Thus it's
possible for someone else to kill the state after it passed the
validity check, and then the insertion will add the dead state
to the cache.

Fix this by moving the validity check inside the lock.

This entire function is called on the input path, where BH must
be off (e.g., the caller of this function xfrm_input acquires
its spinlocks without disabling BH).

So there is no need to disable BH here or take the RCU read lock.
Remove both and replace them with an assertion that trips if BH
is accidentally enabled on some future calling path.

Carlos Song 218cfe364b i2c: imx-lpi2c: mark I2C adapter when hardware is powered down
On some i.MX platforms, certain I2C client drivers keep a periodic
workqueue which continues to trigger I2C transfers.

During system suspend/resume, there exists a time window between:
  - suspend_noirq and the system entering suspend
  - the system starting to resume and resume_noirq

In this window, the I2C controller resources such as clock and pinctrl
may already be disabled or not yet restored.

If a workqueue triggers an I2C transfer in this period, the driver
attempts to access I2C registers while the hardware resources are
unavailable, which may lead to system hang.

Mark the I2C adapter as suspended during noirq suspend and block new
transfers until resume, ensuring that I2C transfers are only issued
when hardware resources are available.

Xu Rao 7d69804a35 ALSA: usb-audio: qcom: Free sideband sg_table objects
The Qualcomm USB audio offload driver obtains an endpoint transfer-ring
table by calling xhci_sideband_get_endpoint_buffer(). This getter passes
the endpoint ring to xhci_ring_to_sgtable(), which allocates the outer
struct sg_table with kzalloc_obj(*sgt). The event-ring path is
equivalent: xhci_sideband_get_event_buffer() also returns the result of
xhci_ring_to_sgtable().

Inside xhci_ring_to_sgtable(), sg_alloc_table_from_pages() separately
allocates the scatterlist storage referenced by sgt->sgl. The returned
object therefore has two allocation layers: the outer struct sg_table
and its internal scatterlist storage.

The Qualcomm caller only invokes sg_free_table(sgt). sg_free_table()
releases the scatterlist storage owned by the table, but it does not
free the separately allocated outer struct sg_table. The local sgt
pointer is then discarded, so every successful endpoint or event-ring
query leaks the outer object.

Call kfree(sgt) after sg_free_table(sgt) in both setup paths, after the
required page and DMA addresses have been copied out.

Galen Hassen f7c4968ae3 ALSA: hda/conexant: Add pin config quirk for Lenovo IdeaPad Slim 5 16AKP10
The Lenovo IdeaPad Slim 5 16AKP10 (PCI SSID 17aa:38b6) uses the
Conexant SN6140 codec. The internal microphone is on pin 0x1a but
the BIOS configures it with pin default 0x95a60120, which includes
a jack detection bit that causes the kernel to treat it as an
unplugged external mic rather than a fixed internal mic.

Add a pin config quirk that overrides pin 0x1a to 0x95a60130,
setting the connectivity bits to indicate a fixed/always-connected
device. This allows the internal microphone to be correctly
identified and used.

Cássio Gabriel 4a60127deb ALSA: compress: Fix task creation error unwind
snd_compr_task_new() allocates the driver task before validating the
returned DMA buffers and reserving file descriptors. When either of
those later steps fails, the core frees its task wrapper and DMA-buffer
references without calling the driver's task_free() callback. Any
driver resources allocated by task_create() are therefore leaked.

The dual-fd allocation path also jumps to cleanup without storing the
negative get_unused_fd_flags() result in retval. Since retval still
contains the successful task_create() return value, TASK_CREATE can
incorrectly report success although the task was discarded.

Preserve the fd allocation errors and call task_free() when failure
occurs after a successful task_create() callback.

Guillermo Rodríguez 111bb7f9f4 i2c: stm32f7: truncate clock period instead of rounding it
stm32f7_i2c_compute_timing() derives the I2C clock source period
(i2cclk) with DIV_ROUND_CLOSEST, which may round it up. When the
period is overestimated, all timings computed from it (SCLDEL,
SDADEL, SCLL, SCLH) come out shorter on the wire than calculated,
and the resulting bus rate can exceed the requested speed, violating
the I2C specification minimums for tLOW and tHIGH.

For example, with a 104.45 MHz clock source (e.g. PCLK1, the
reset-default I2C clock source on STM32MP1), i2cclk is rounded from
9.574 ns up to 10 ns. Requesting a 400 kHz fast mode bus with
72/27 ns rise/fall times and no analog/digital filters then produces
an actual bus rate of 415.6 kHz with tLOW = 1254 ns, violating both
the 400 kHz maximum rate and the 1300 ns tLOW minimum of the
specification.

Truncate the period instead, so that it can only be underestimated.
The error then falls on the safe side: the programmed timings come
out slightly longer than computed and the bus runs marginally below
the target rate (375.3 kHz in the example above) while meeting the
specification.

i2cbus is left rounded-to-closest: it is only used as the target of
the clk_error comparison and is never multiplied into the programmed
timings, so nearest rounding remains accurate there.

Linus Torvalds 9c87e61e3c Merge tag 'bpf-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Pull bpf updates from Alexei Starovoitov:
 "Major changes:

   - Recover from BPF arena page faults using a scratch page and add
     ptep_try_set() for lockless empty-slot installs on x86 and arm64.

     This allows BPF kfuncs to access arena pointers directly.

     The 'arena_direct_access' stable branch was created for this work
     and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar
     Kartikeya Dwivedi)

   - Lift old restriction and support 6+ arguments in BPF programs and
     kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan)

  Other features and fixes:

   - Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease
     addition of new BTF kinds (Alan Maguire)

   - Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei
     Starovoitov)

   - Refactor object relationship tracking in the verifier and fix a
     dynptr use-after-free bug (Amery Hung)

   - Harden the signed program loader and reject exclusive maps as inner
     maps (Daniel Borkmann)

   - Replace the verifier min/max bounds fields with a circular number
     (cnum) representation and improve 32->64 bit range refinements
     (Eduard Zingerman)

   - Introduce the arena library and runtime (libarena) with a buddy
     allocator, rbtree and SPMC queue data structures, ASAN support and
     a parallel test harness. Allow subprograms to return arena pointers
     and switch to a BTF type-tag based __arena annotation (Emil
     Tsalapatis)

   - Cache build IDs in the sleepable stackmap path and avoid faultable
     build ID reads under mm locks (Ihor Solodrai)

   - Introduce the tracing_multi link to attach a single BPF program to
     many kernel functions at once. Allow specifying the uprobe_multi
     target via FD (Jiri Olsa)

   - Extend the bpf_list family of kfuncs with bpf_list_add/del(), and
     bpf_list_is_first/is_last/empty() (Kaitao Cheng)

   - Extend the BPF syscall with common attributes support for
     prog_load, btf_load and map_create (Leon Hwang)

   - Wrap rhashtable as BPF map (Mykyta Yatsenko, Herbert Xu)

   - Add sleepable support for tracepoint programs and fix deadlocks in
     LRU map due to NMI reentry (Mykyta Yatsenko)

   - Fix OOB access in bpf_flow_keys, fix nullness analysis of inner
     arrays, enforce write checks for global subprograms (Nuoqi Gui)

   - Report the maximum combined stack depth and print a breakdown of
     instructions processed per subprogram (Paul Chaignon)

   - Add an XDP load-balancer benchmark and arm64 JIT support for stack
     arguments (Puranjay Mohan)

   - Add kfuncs to traverse over wakeup_sources (Samuel Wu)

   - Allow sleepable BPF programs to use LPM trie maps directly (Vlad
     Poenaru)

   - Many more fixes and cleanups across the verifier, BTF, sockmap,
     devmap, bpffs, security hooks, s390/riscv/loongarch JITs,
     rqspinlock, libbpf, bpftool, selftests"
