bb76cc45dc iio: gts-helper: Fix division loop 
The loop based 64bit division may run for a long time when dividend is a
lot bigger than the divider. Replace the division loop by the
div64_u64() which implementation may be significantly faster.

3ad0e7e5f0 iio: humidity: hdc3020: add threshold events support 
Add threshold events support for temperature and relative humidity. To
enable them the higher and lower threshold registers must be programmed
and the higher threshold must be greater then or equal to the lower
threshold. Otherwise the event is disabled. Invalid hysteresis values
are ignored by the device. There is no further configuration possible.

Tested by setting thresholds/hysteresis and turning the heater on/off.
Used iio_event_monitor in tools/iio to catch events while constantly
displaying temperature and humidity values.

Enable the voltage divider to both receive and provide measurement
services by adding #io-channel-cells.

This is especially valuable in scenarios where an ADC has an analog

ca2f16c315 Add 10EC5280 to bmi160_i2c ACPI IDs to allow binding on some devices 
"10EC5280" is used by several manufacturers like Lenovo, GPD, or AYA (and
probably others) in their ACPI table as the ID for the bmi160 IMU. This
means the bmi160_i2c driver won't bind to it, and the IMU is unavailable
to the user. Manufacturers have been approached on several occasions to
try getting a BIOS with a fixed ID, mostly without actual positive
results, and since affected devices are already a few years old, this is
not expected to change. This patch enables using the bmi160_i2c driver for
the bmi160 IMU on these devices.

Here is the relevant extract from the DSDT of a GPD Win Max 2 (AMD 6800U
model) with the latest firmware 1.05 installed. GPD sees this as WONTFIX
with the argument of the device working with the Windows drivers.

	Device (BMA2)
	{
	    Name (_ADR, Zero)  // _ADR: Address
	    Name (_HID, "10EC5280")  // _HID: Hardware ID
	    Name (_CID, "10EC5280")  // _CID: Compatible ID
	    Name (_DDN, "Accelerometer")  // _DDN: DOS Device Name
	    Name (_UID, One)  // _UID: Unique ID
	    Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings

f7b6443f34 iio: sx9324: avoid copying property strings 
We're doing some needless string copies when trying to assign the proper
`prop` string. We can make `prop` a const char* and simply assign to
string literals.

For the case where a format string is used, let's extract the parsing
logic out into sx9324_parse_phase_prop(). We no longer need to create
copies or allocate new memory.

sx9324_parse_phase_prop() will simply return the default def value if it
fails.

This also cleans up some deprecated strncpy() uses [1].

Furthermore, let's clean up this code further by removing some unused
defines:
|  #define SX9324_PIN_DEF "semtech,ph0-pin"
|  #define SX9324_RESOLUTION_DEF "semtech,ph01-resolution"
|  #define SX9324_PROXRAW_DEF "semtech,ph01-proxraw-strength"

cf996f0396 iio: test: test gain-time-scale helpers 
Some light sensors can adjust both the HW-gain and integration time.
There are cases where adjusting the integration time has similar impact
to the scale of the reported values as gain setting has.

IIO users do typically expect to handle scale by a single writable 'scale'
entry. Driver should then adjust the gain/time accordingly.

It however is difficult for a driver to know whether it should change
gain or integration time to meet the requested scale. Usually it is
preferred to have longer integration time which usually improves
accuracy, but there may be use-cases where long measurement times can be
an issue. Thus it can be preferable to allow also changing the
integration time - but mitigate the scale impact by also changing the gain
underneath. Eg, if integration time change doubles the measured values,
the driver can reduce the HW-gain to half.

The theory of the computations of gain-time-scale is simple. However,
some people (undersigned) got that implemented wrong for more than once.
Hence some gain-time-scale helpers were introduced.

Add some simple tests to verify the most hairy functions.

44b9038345 iio: light: vcnl4000: Set ps high definition for 4040/4200 
The vcnl4040/vcnl4200 proximity sensor defaults to 12 bit data
resolution, but the chip also supports 16 bit data resolution, which is
called proximity high definition (PS_HD).

Make the vcnl4040/vcnl4200 proximity sensor use the high definition for
all data readings. Please note that in order to preserve the 12 bit
integer part of the in_proximity_raw output, the format is changed from
integer to fixed point.

1ca53b5df1 iio: adc: ad_sigma_delta: allow overwriting the IRQ flags 
Make sure we can specify the IRQ trigger type from firmware and drivers
won't ignore it. In fact, this how it should be done but since someone
might be already depending on the driver to hardcode the trigger type
(and not specifying it in firmware), let's do it like this so there's
no possible breakage.

4e6500bfa0 tools: iio: replace seekdir() in iio_generic_buffer 
Replace seekdir() with rewinddir() in order to fix a localized glibc bug.

One of the glibc patches that stable Gentoo is using causes an improper
directory stream positioning bug on 32bit arm. That in turn ends up as a
floating point exception in iio_generic_buffer.

The attached patch provides a fix by using an equivalent function which
should not cause trouble for other distros and is easier to reason about
in general as it obviously always goes back to to the start.
