iio: tsl2583: Fix division by a zero lux_val
The lux_val returned from tsl2583_get_lux can potentially be zero,
so check for this to avoid a division by zero and an overflowed
gain_trim_val.
Fixes clang scan-build warning:
drivers/iio/light/tsl2583.c:345:40: warning: Either the
condition 'lux_val<0' is redundant or there is division
by zero at line 345. [zerodivcond]

iio: light: gp2ap002: Fix rumtime PM imbalance on error
When devm_request_threaded_irq() fails, we should decrease the
runtime PM counter to keep the counter balanced. But when
iio_device_register() fails, we need not to decrease it because
we have already decreased it before.

1st set of IIO/counter device support, features and cleanup in the 5.13 cycle
Big set in here from Alexandru Ardelean enabling multiple buffer support.
This includes providing a new directory per buffer that combines
what was previously in buffer/ and scan_elements/. Old interfaces still
in place for compatiblity.
Note immuatable branch for scmi patches to allow for some significant
rework going on in that subsystem. Merge required updating to reflect
some changes in IIO.
Late rebase to fix some wrong fixes tags due to some earlier rebases
made necessary by messing up the immutable branch.
IIO New Device Support
* adi,ad5686
- Add info to support AD5673R and AD5677R
* bosch,bmi088
- New driver supporting this accelerometer + gyroscope
* cros_ec_mkbp
- New driver for this proximity sensor that exposes a 'front'
sensor. Very simple switch like device, but driver allows it
to share interface with more sophisticated proximity sensors.
* iio_scmi
- New driver to support ARM SCMI protocol to expose underlying
accelerometers and gyroscopes via this firmware interface.
* st,st_magn
- Add ID for IISMDC magnetometer.
* ti,ads131e0
- New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
Counter New Device Support
* IRQ or GPIO based counter
- New driver for a conceptually simple counter that uses interrupts
to perform the count.
Features
* core
- Dual buffer supprt including:
Various helpers to centralize handling of bufferer related elements.
Document existing and new IOCTLs
Register the IIO chrdev only if it can actually be used for anything.
Rework attribute group creation in the core (lots of patches)
Merge buffer/ and scan_elements/ entries into one list + maintain
backwards compatible set.
Introduce the internal logic and IOCTL to allow multiple buffers
+ access to an anon FD per buffer to actually read from it.
Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
Update ABI docs.
A few follow up fixes, unsuprising as this was a huge bit of rework.
- Move common case setting of trig->parent to the core.
- Provide an iio_read_channel_processed_scale() to avoid loss of
precision from iio_read_channel_processed() then applying integer
scale. Use it in ntc_thermistor driver in hwmon.
- Allow drivers to specify labels from elsewhere than DT. Use it for
bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
- Document label usage for proximity and accelerometer sensors.
- Some local variable renames for consistency
tools
- Add -a parameter to iio_event_monitor to allow autoenabling of events.
* acpi_als
- Add trigger support for devices that don't support notification method.
* adi,ad7124
- Allow more than 8 channels. This is a complex little device, but is
capable of supporting up to 16 channels if the share certain
configuration settings.
* hrtimer-trigger
- Support sampling frequency below 1Hz.
* mediatek,mt8195-auxadc
- Add compatible to binding docs (always also includes mt8173)
* st,stm32-adc
- Enable timetamps when not using DMA.
* vishay,vcnl3020
- Sampling frequency control.
Cleanup and minor fixes:
* treewide
- Use some getter and setter functions instead of opencoding.
- Set of fixes for pointless casts in various drivers.
- Avoid wrong kernel-doc marking on comment blocks.
- Fix various other minor kernel-doc issues shown by W=1
* core
- Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
- Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
- Add unit tests for iio_format_value()
* docs
- Fix formatting/typos in iio_configfs.rst and buffers.rst
- Add documentation of index in buffers.rst
- Fix scan element description
- Avoid some issues with HTML generation from ABI docs by moving
duplicated defintions to more generic files.
- Drop reference to long dead mailing list.
* 104-quad
- Remove left over deprecated IIO counter ABI.
* adi,adi-axi-adc
- Fix wrong bit of docs.
* adi,ad5791
- Typos
* adi,ad9834
- Switch to device managed functions in probe.
* adi,adis*
- Add and use helpers for locking to reduced duplication.
* adi,adis16480
- Fix calculation of sampling frequency when using pulse per second input.
* adi,adis16475
- Calculate the IMU scaled internal sampling rate and runtime depending
on sysfs based configuration rather than getting from DT. Drop now
unnecessary property from DT bindings doc.
* cros_ec
- Fix result of a series of recent changes that means extended buffer
attributes turn up in the wrong place. Too complex to revert the
various patches unfortunately so this is a bit messy.
* fsl,mma3452
- Indentation cleanup.
* hid-sensors
- Size of storage needs to increase for some parts when using quaternions.
- Move the get sensistivity attribute to hid-sensors-common to reduce
duplication. Enable it for more device types.
- Correctly handle relative sensitivity if reported that way including
documenting the new ABI.
* maxim,max517
- Use device managed functions in probe.
* mediatek,mt6360-adc
- Use asm/unaligned.h instead of directly including
unaligned/be_byteshift.h
* novuton,npcm-adc
- Local lock instead of missusing mlock.
* semtech,sx9500
- Typos
* st,sensor
- typo fix

iio: acpi_als: Add trigger support
As some firmware does not notify on illuminance changes, add a
trigger to be able to query light via software (sysfs-trigger or
hrtrigger).
Add a hardware trigger set as the default trigger to maintain backward
compatibility.
Check iio_info reports the sensor as buffer capable:
iio:device0: acpi-als (buffer capable)
To test, check we can get data on demand on an Intel based chromebook:
IIO_DEV="iio:device0"
echo 1 > iio_sysfs_trigger/add_trigger

iio: gp2ap020a00f: Remove code to set trigger parent
iio_trigger_set_drvdata() sets the trigger device parent to first argument of viio_trigger_alloc(), no need to do it again in the driver code. Given data->client is client, and we call devm_iio_trigger_alloc() with &client->dev, we do not have to set data->trig->dev.parent to &data->client->dev anymore.

Prototype was for <function>() instead
To reproduce the errors:
scripts/kernel-doc -v -none $(find drivers/iio/ -name \*.c \
-exec head -2 {} \+ | grep -B2 -e '\*\*' | grep '==' | cut -d ' ' -f 2)

iio: make use of devm_iio_kfifo_buffer_setup() helper
All drivers that already call devm_iio_kfifo_allocate() & iio_device_attach_buffer() are simple to convert to iio_device_attach_kfifo_buffer() in a single go. This change does that; the unwind order is preserved. What is important, is that the devm_iio_kfifo_buffer_setup() be called after the indio_dev->modes is assigned, to make sure that INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to indio_dev->modes. Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of 'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

iio:light:st_uvis25: Fix timestamp alignment and prevent data leak.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp() assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv()
This data is allocated with kzalloc() so no data can leak apart
from previous readings.
A local unsigned int variable is used for the regmap call so it
is clear there is no potential issue with writing into the padding
of the structure.

The forced alignment of ts is not necessary in this case but it
potentially makes the code less fragile.
>From personal communications with Mikko:
We could probably split the reading of the int register, but it
would mean a significant performance cost of 20 i2c clock cycles.

iio: light: fix kconfig dependency bug for VCNL4035
When VCNL4035 is enabled and IIO_BUFFER is disabled, it results in the
following Kbuild warning:
WARNING: unmet direct dependencies detected for IIO_TRIGGERED_BUFFER
Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
Selected by [y]:
- VCNL4035 [=y] && IIO [=y] && I2C [=y]
The reason is that VCNL4035 selects IIO_TRIGGERED_BUFFER without depending
on or selecting IIO_BUFFER while IIO_TRIGGERED_BUFFER depends on
IIO_BUFFER. This can also fail building the kernel.
Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.
Fixes:

iio: cros_ec: unify hw fifo attributes into the core file
The intent here is to minimize the use of iio_buffer_set_attrs(). Since we are planning to add support for multiple IIO buffers per IIO device, the issue has to do with: 1. Accessing 'indio_dev->buffer' directly (as is done with 'iio_buffer_set_attrs(indio_dev->buffer, <attrs>)'). 2. The way that the buffer attributes would get handled or expanded when there are more buffers per IIO device. Current a sysfs kobj_type expands into a 'device' object that expands into an 'iio_dev' object. We will need to change this, so that the sysfs attributes for IIO buffers expand into IIO buffers at some point. Right now, the current IIO framework works fine for the '1 IIO device == 1 IIO buffer' case (that is now).

Second set of features and cleanups for IIO in 5.10
We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.
There are a few late breaking fixes in here that can wait for the
merge window.

iio:light:si1145: Fix timestamp alignment and prevent data leak.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses a 24 byte array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable array in the iio_priv() data with alignment
explicitly requested. This data is allocated with kzalloc so no
data can leak appart from previous readings.
Depending on the enabled channels, the location of the timestamp
can be at various aligned offsets through the buffer. As such we
any use of a structure to enforce this alignment would incorrectly
suggest a single location for the timestamp. Comments adjusted to
express this clearly in the code.

Staging / IIO driver fixes for 5.9-rc5
Here are a number of Staging and IIO driver fixes for 5.9-rc5. The majority of these are IIO driver fixes, to resolve a timestamp issue that was recently found to affect a bunch of IIO drivers. The other fixes in here are: - small IIO driver fixes - greybus driver fix - counter driver fix (came in through the IIO fixes tree) All of these have been in linux-next for a while with no reported issues.

iio: light: as73211: Increase measurement timeout
We found some sensors which are much slower (20% at room temperature)
than nominal. According to the data sheet, up to 27% is possible. Now I
add 33% to the nominal time out, hopefully this is enough.

iio: light: as73211: New driver
Support for AMS AS73211 JENCOLOR(R) Digital XYZ Sensor. This driver has no built-in trigger. In order for making triggered measurements, an external (software) trigger driver like iio-trig-hrtimer or iio-trig-sysfs is required. The sensor supports single and continuous measurement modes. The latter is not used by design as this would require tight timing synchronization between hardware and driver without much benefit.

iio:light:ltr501 Fix timestamp alignment issue.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
Here we use a structure on the stack. The driver already did an
explicit memset so no data leak was possible.
Forced alignment of ts is not strictly necessary but probably makes
the code slightly less fragile.
Note there has been some rework in this driver of the years, so no
way this will apply cleanly all the way back.

iio:light:max44000 Fix timestamp alignment and prevent data leak.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses a 16 byte array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv().
This data is allocated with kzalloc so no data can leak appart
from previous readings.
It is necessary to force the alignment of ts to avoid the padding
on x86_32 being different from 64 bit platorms (it alows for
4 bytes aligned 8 byte types.

Replace HTTP links with HTTPS ones: drivers/iio
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.
