dev->host_mem_size value is updated only after the successful buffer
allocation of hmb descriptor. Otherwise, it may have some undefined value.
So, use the correct size to free the hmb buffer when the hmb descriptor
buffer allocation failed.

The xa_store() may fail due to memory allocation failure because there
is no guarantee that the index NVME_CSI_NVM is already used. This fix
introduces a new function to handle the error path.

The recently added WARN() for deprecated #address-cells and #size-cells
triggered a WARN when of_platform_populate() (which calls
of_address_to_resource()) is used on nodes with non-translatable
addresses. This case is expected to return an error.
Rework the bus matching to allow no match and make the default require
an #address-cells property. That should be safe to do as any platform
missing #address-cells would have a warning already.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on
static/build-time data. Dtschema and Devicetree bindings offer the
static/build-time check for this already.

Clear reset status flag, to keep error status register
clean after reset (ad3552r manual, rev B table 38).
Reset error flag was left to 1, so debugging registers, the
"Error Status Register" was dirty (0x01). It is important
to clear this bit, so if there is any reset event over normal
working mode, it is possible to detect it.

Fix ad3541/2r voltage ranges to be as per ad3542r datasheet,
rev. C, table 38 (page 57).
The wrong ad354xr ranges was generating erroneous Vpp output.
In more details:
- fix wrong number of ranges, they are 5 ranges, not 6,
- remove non-existent 0-3V range,
- adjust order, since ad3552r_find_range() get a wrong index,
producing a wrong Vpp as output.

Currently the userspace and kernel filters for guests are never set, so
no trace will be generated for them. Add support for tracing guests by
passing the desired TRFCR value to KVM so it can be applied to the
guest.
By writing either E1TRE or E0TRE, filtering on either guest kernel or
guest userspace is also supported. And if both E1TRE and E0TRE are
cleared when exclude_guest is set, that option is supported too. This
change also brings exclude_host support which is difficult to add as a
separate commit without excess churn and resulting in no trace at all.
cpu_prohibit_trace() gets moved to TRBE because the ETM driver doesn't
need the read, it already has the base TRFCR value. TRBE only needs
the read to disable it and then restore.
Testing
=======
The addresses were counted with the following:
$ perf report -D | grep -Eo 'EL2|EL1|EL0' | sort | uniq -c
Guest kernel only:
$ perf record -e cs_etm//Gk -a -- true
535 EL1
1 EL2
Guest user only (only 5 addresses because the guest runs slowly in the
model):
$ perf record -e cs_etm//Gu -a -- true
5 EL0

$ perf record -e cs_etm//Hk -a -- true
3501 EL2

Currently in nVHE, KVM has to check if TRBE is enabled on every guest
switch even if it was never used. Because it's a debug feature and is
more likely to not be used than used, give KVM the TRBE buffer status to
allow a much simpler and faster do-nothing path in the hyp.
Protected mode now disables trace regardless of TRBE (because
trfcr_while_in_guest is always 0), which was not previously done.
However, it continues to flush whenever the buffer is enabled
regardless of the filter status. This avoids the hypothetical case of a
host that had disabled the filter but not flushed which would arise if
only doing the flush when the filter was enabled.

trbe_drain_and_disable_local() just clears TRBLIMITR and drains.
TRBLIMITR is already cleared on the next line after this call, so
replace it with only drain. This is so we can make a kvm call that has a
preempt enabled warning from set_trbe_disabled() in the next commit,
where trbe_reset_local() is called from a preemptible hotplug path.

Pull IIO updaate from Jonathan:
IIO: 1st set of new device support, features and cleanup for 6.14
Fairly quiet cycle. Usual mix of new drivers, device support in
existing drivers, features and more general rework and cleanup.
There are a few late breaking or long standing but complex fixes
in here as well.
There is one expected merge conflict due to an upstream fix touching
neighboring code in ti-ads1119. The trivial resolution is the right one with
the result ending up as:
struct {
s16 sample;
aligned_s64 timestamp;
} scan;
New device support
==================
adi,ad4000
- Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688,
AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984,
AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series
but with lower sampling rates and no configuration registers.
Includes addition of timestamp channels.
adi,adis16480
- Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks
to existing driver and addition of tables.
kionix,kx022a
- Add support for KX134ACR-LBZ accelerometer that is similar to the
KX132ACR-LBZ but with a wider (+-64G) sensor range.
- Add support for KX134-1211 accelerometer that is similar to the
KX132-1211 but with a wider (+-16G) sensor range.
nxp,fxls8962af
- Add support for fxls8974cf and fxls8967af accelerometers, Both are
compatible with fxls8962af but with different device IDs which are used in
presence checks.
renesas,rzg2l
- Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors
precede this to allow for chip differences).
rohm,bd79704
- New driver for this 6 channel DAC.
st,mpu6050
- Support he IAM20380 which is effectively a cut down IAM20608 IMU with only
a gyroscope (no accelerometer).
st,stm-timmer-trigger
- Add support for ADC trigger use case for the STM32MP25 SOC. Do not support
the counter functionality in this driver as that is handled by the
counter subsystem.
ti,opt4060
- New driver for this RGBW color sensor.
Driver drop
===========
rohm,bu20008
- Drop as decision was made to not mass produce this light sensor after
Matti had done all the work to get a driver upstream.
Features
========
adi,ad_sigma_delta library + ad7124
- Allow for GPIO to check interrupt status, enabling this device on
more platforms that don't obey prior (non general) assumptions on
how the interrupt chips work.
- Allow variation in reset sequence length allowing chip specific
optimizations rather than always using worst case.
adi,ad7124
- Add temperature channel support.
adi,ad7173
- Add support calibration modes for this family of ADCs.
adi,adxl345
- Binding update to allow specification of which interrupt line is
connected (or none).
- Support interrupts and FIFO based data capture.
bosch,bme680
- Add regulators support. Note this required a new binding doc rather than
use of trivial-devices
- Runtime PM support.
microchip,pac1921
- Add ACPI support including _DSM for shunt value and label.
renesas,rzg2l
- Enable runtime autosuspend.
- Add suspend and resume support.
tyhx,hx9023s
- Add loading of a firmware file used to set defaults for some
configuration registers.
vishay,veml6030
- Support triggered buffers allowing efficient data capture at
higher speeds.
- Add regmap cache to reduce access to device.
Cleanup and minor fixes
=======================
cross-tree
- Another batch of conversions to devm_regulator_get_enable_read_voltage()
helper and related conversions to full devm that this enables.
- Various patches using guard() to allow early returns and simpler
code flow.
- Various conversions from s64 timestamp __aligned(8) to aligned_s64 type.
Includes a few cleanups where this unsigned and it should have been
signed.
- Fix up some missing types for drive-open-drain in dt-binding docs.
core
- Add missing documentation for iio_dmaengine_buffer_setup_ext()
- Add check that all buffers passed to iio_read_channel_ext_info()
and iio_read_channel_label() are page sized and page aligned.
Done this way because the callbacks are almost always only used
to fill sysfs attributes. The check covers the tiny percentage
of cases where use is made of this data in a consumer driver.
- Mark scan_timestamp memory of struct iio_dev private ensuring no
drivers change the value which belongs to the IIO core.
documentation
- Various missing ABI docs added.
- ABI docs made to use Y consistently as the wildcard for channel
number.
- Combine duplicate in_currentY_raw entries in ABI docs.
iio-mux
- Fix alignment of buffers passed to iio_channel_read_ext_info().
adi,ad_sigma_delta library
- Respect keep_cs_asserted flag in read path.
- Close a race condition around irq enabling and disabling.
- Use explicit unsigned int in place of unsigned.
adi,ad6695
- Move dt-binding header under adc sub-directory and fix include path in dt
example.
adi,ad7124
- Check number of channels in DT doesn't exceed what the driver can handle.
- Check input specified in DT are possible.
- Improved error reporting during probe.
adi,ad7173
- Drop unused structure element.
adi,ad7293
- Ensure power is turned on before resetting.
adi,adxl345
- Some documentation simplification and parameter renames.
- Add a function than unifies handling of power up and power down.
- Add defines to have a complete set of registers defined.
- Add missing \n to end of error messages.
amlogic,meson_saradc
- Simplify handling of the REG11 register access.
awinic,aw96104
- Constify iio_info structure.
bosch,bmp085
- Add to dt-binding to indicate devices support SPI.
bosch,bmp280
- Use sizeof() to replace a somewhat magic 2.
- Rename sleep related variables so the unit is included and use
fsleep() to replace usleep_range() calls.
bosch,bno055
- Constify struct bin_attribute
capella,cm3232
- Reset device before checking hardware ID inline with suggested flow
from datasheet.
diolan,dln2
- Simplify zeroing of structure used to gather up data by just
clearing the whole thing before writing rather than trying to
clear out he padding after write.
freescale,vf610
- Use devm_ and dev_error_probe() to simplify code and allow dropping
of explicit remove() callback.
invensense,timestamp library
- Use a cast to remove possibility of integer overflow.
kionix,kx022a
- Increase reset delay a little.
maxim,max1363
- Use a buffer of sufficient size in iio_priv() rather than allocating
variable sized buffer at use time.
microchip,mcp4725
- Replace of_property_read_bool() with of_property_present() for
detecting presence of regulator which is obviously not a bool.
nxp,fxls8962af
- Add wakeup-source property to the dt binding to allow these sensors
to wake the system up from suspend.
- Enable finer grained build when not all bus types need to be supported.
renesas,rzg2l
- Use dev_err_probe(), improving handling of probe errors and simplifying
code.
- Convert to devm_ based cleanup.
- Remove unnecessary runtime PM complexity as clocks are managed through
PM domains.
- Switch pm_ptr() removing need for __maybe_unused markings.
- use read_poll_timeout() to replace open coded equivalent.
samsung, ssp_sensors
- Simplify code by always providing timestamp whether or not it
is enabled.
st,lsm6dsx
- Avoid need to include linux/i3c/master by using i3cdev_to_dev() to
get to the contained struct device.
st,stm32-timer-trigger
- Check for clk_enable() fails.
vishay,veml6030
- Use new gts-helper functions and fix the _scale attribute to take into
account changes in gain and integration time.
Various other typo fixes in variable names + documentation and help text.
A few whitespace cleanup patches.

Register a struct led_classdev with the kernel's LED subsystem and
create a throughput-based trigger for it. Then mac80211 makes the LED
blink.
Tested with Tenda U12 (RTL8812AU), Tenda U9 (RTL8811CU), TP-Link Archer
T2U Nano (RTL8811AU), TP-Link Archer T3U Plus (RTL8812BU), Edimax
EW-7611UCB (RTL8821AU), LM842 (RTL8822CU).

disconnection after beacon loss") for SDIO chips.
Tested on Pinephone (RTL8723CS), random disconnections became rare,
instead of a frequent nuisance.

Fix 3 typos in 8703b driver. 2 typos in calibration routines are not
fatal and do not seem to have any impact, just fix them to match vendor
driver.
However the last one in rtw8703b_set_channel_bb() clears too many bits
in REG_OFDM0_TX_PSD_NOISE, causing TX and RX issues (neither rate goes
above MCS0-MCS1). Vendor driver clears only 2 most significant bits.
With the last typo fixed, the driver is able to reach MCS7 on Pinebook

The rtwdev->scanning flag isn't protected by mutex originally, so
cancel_hw_scan can pass the condition, but suddenly hw_scan completion
unset the flag and calls ieee80211_scan_completed() that will free
local->hw_scan_req. Then, cancel_hw_scan raises null-ptr-deref and
use-after-free. Fix it by moving the check condition to where
protected by mutex.

For each MCC role, time limits, including max_tob_us, max_toa_us, and
mac_dur_us, are calculated if there are NoA attributes. The relation
between these time limits is "max_dur_us = max_tob_us + max_toa_us".
Then, the unit is converted from us to TU. However, originally, each
time limit was divided by 1024 independently. It missed to consider
the cases that max_tob_us or max_toa_us is not divisible by 1024. It
causes the result breaks "max_dur (TU) = max_tob (TU) + max_toa (TU)".
Finally, when MCC calculates pattern parameters based on these kinds
of time limits, it might not perform well.

For early chips, the RX BD info contains FS/LS bits for first/last segments
of a receiving packet. For 8922AE, the FS bit should be ignored, or it
may throw warning:
rtw89_8922ae 0000:1a:00.0: skb should not be ready before first segment start
To have compatible logic, FS determined by what pending skb is existing
(!new) or not.
Since we expect every single receiving packet in single one segment,
enlarge 4 bytes for RX BD info, and add a debug message to note if
RX buffer is possibly smaller than expected size.

If WoWLAN failed in resume flow, the rtw89_ops_add_interface() triggered
without removing the interface first. Then the mgnt_entry list init again,
causing the list_empty() check in rtw89_chanctx_ops_assign_vif()
useless, and list_add_tail() again. Therefore, we have added a check to
prevent double adding of the list.

During rtw89_entity_recalc_mgnt_roles(), there is a normalizing process
which will re-order the list if an entry with target pattern is found.
And once one is found, should have aborted the list_for_each_entry. But,
`break` just aborted the inner for-loop. The outer list_for_each_entry
still continues. Normally, only the first entry will match the target
pattern, and the re-ordering will change nothing, so there won't be
soft lockup. However, in some special cases, soft lockup would happen.
Fix it by `goto fill` to break from the list_for_each_entry.
The following is a sample of kernel log for this problem.

When starting/proceeding MCC, it will abort an ongoing hw scan process.
In the proceeding cases, it unexpectedly tries to abort a non-exist hw
scan process. Then, a trace shown at the bottom will happen. This problem
is caused by a previous commit which changed some call sequence inside
rtw89_hw_scan_complete() to fix some coex problems. These changes lead
to our scanning flag was not cleared when proceeding MCC. To keep the
fixes on coex, and resolve the problem here, re-consider the related
call sequence.
The known sequence requirements are listed below.
* the old sequence:
A. notify coex
B. clear scanning flag
C. proceed chanctx
C-1. set channel
C-2. proceed MCC
(the problem: A needs to be after C-1)
* the current sequence:
C. proceed chanctx
C-1. set channel
C-2. proceed MCC
A. notify coex
B. clear scanning flag
(the problem: C-2 needs to be after B)
So, now let hw scan caller pass a callback to proceed chanctx if needed.
Then, the new sequence will be like the below.
C-1. set channel
A. notify coex
B. clear scanning flag
C-2. proceed MCC
The following is the kernel log for the problem in current sequence.

The DP83822 supports up to three configurable Light Emitting Diode (LED)
pins: LED_0, LED_1 (GPIO1), COL (GPIO2) and RX_D3 (GPIO3). Several
functions can be multiplexed onto the LEDs for different modes of
operation. LED_0 and COL (GPIO2) use the MLED function. MLED can be routed
to only one of these two pins at a time. Add minimal LED controller driver
supporting the most common uses with the 'netdev' trigger.

When inserting a USB device, examining hcd->rsrc_start can be
helpful in identifying which hcd is mounted, as the physical
address represented here is typically unique.
The following code snippet demonstrates this:
struct usb_hcd *hcd = bus_to_hcd(udev->bus);
unsigned long long usb_hcd_addr = (unsigned long long)hcd->rsrc_start;
However, this approach has limitations now. For USB hosts with an
MMIO interface, the effectiveness of this method is restricted to
USB 2.0.
Because commit 3429e91a661e ("usb: host: xhci: add platform driver
support") assigned res->start to hcd->rsrc_start. But
shared_hcd->rsrc_start remains unassigned, which is also necessary
in certain scenarios.
Fixes: 3429e91a661e ("usb: host: xhci: add platform driver support")

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based kernel configuration guards.

When the system begins to enter suspend mode, dwc3_suspend() is called
by PM suspend. There is a problem that if someone interrupt the system
suspend process between dwc3_suspend() and pm_suspend() of its parent
device, PM suspend will be canceled and attempt to resume suspended
devices so that dwc3_resume() will be called. However, dwc3 and its
parent device (like the power domain or glue driver) may already be
suspended by runtime PM in fact. If this sutiation happened, the
pm_runtime_set_active() in dwc3_resume() will return an error since
parent device was suspended. This can lead to unexpected behavior if
DWC3 proceeds to execute dwc3_resume_common().
EX.
RPM suspend: ... -> dwc3_runtime_suspend()
-> rpm_suspend() of parent device
...
PM suspend: ... -> dwc3_suspend() -> pm_suspend of parent device
^ interrupt, so resume suspended device
... <- dwc3_resume() <-/
^ pm_runtime_set_active() returns error
To prevent the problem, this commit will skip dwc3_resume_common() and
return the error if pm_runtime_set_active() fails.
