The ILPS22QS is an ultra-compact piezoresistive absolute pressure sensor
which functions as a digital output barometer, supporting dual full-scale
up to user- selectable 4060 hPa. The device delivers ultra-low pressure
noise with very low power consumption and operates over an extended
temperature range from -40 °C to +105 °C.

Add support for Bosch bmp390 sensor, the drop in replacement for the
bmp388 with same register but different chip-id. This patch make use
of "bosch_bmp390" or "bosch_bmp388" and set the specific chip-id in a
data->chip-id variable, which then used to check against the register
value.
Additional, manual shift operation had been replaced with ENDIAN safe
macros and calibration values with target variable of int16_t add a
cast for it.
bmp388_spi: read register implementation wrong, fixed it.
tx-buffer must be <addr><dummy><dummy> in order to receive the
register value. Read registers in burst mode and have rx and tx
buffer same spi_buf to avoid clock stop and delay with nrf5.

The NTC thermistor implementation assumes a constant pull-up voltage
and that the ADC channel is measured against a reference voltage so that
the absolute voltage across the NTC can be calculated. Based on the
relationship of `pullup-uv` and this absolute NTC voltage, the resistance
of the NTC is calculated.
There are applications where the "pullup-uv" is not constant, but VDD.
Most ADCs support relative measurements against VDD. If `pullup-uv` is not
defined, the implementation assumes now that the ADC channel is configured
to use VDD as a reference and therefore no millivolt conversion is
required.

optionally interrupt line.

Update the devicetree binding for the nxp,kinetis-acmp comparator and
move the binding to dts/bindings/comparator.
The update to the binding includes:
- Remove unused io-channel-cells property
- Remove unused sensor-device include
- Adding missing properties dac config, discrete mode config, and
input configs.
- Rename properties to exclude redundant vendor prefix since props in
this binding are not inhereted, and as such, don't need to be
namespaced.
- Deprecate the old names of the renamed properties
The sensor based device driver has been updated to support both the
deprecated and new property names. This allows it to use both
nxp,enable-sample and filter-enable-sample for example.
Additionally, remove the unused io-channel-cells properties from
in-tree nodes of compatible = "nxp,kinetis-acmp"

Change the STM32 Temperature Sensor bindings to accept the average slope
value in string form instead of integer. With this change, it is possible
to use the raw decimal value found in each MCU's datasheet instead of
needing to scale it (differently depending on series!). This also allows
regrouping the property in a single file to reduce duplication.
Also update all DTSI files affected by this change and the dietemp driver
to accept the property's new format.

Reduce duplication in STM32 dietemp bindings by regrouping the 'ntc'
property declared in both "st,stm32-temp" and "st,stm32c0-temp-cal"
to the shared "st,stm32-temp-common" binding.
"st,stm32-temp-cal" is also modified to block 'ntc' property on include as
no dual-calibration sensors to date require it (this could be changed later
when need arises).

Set the 'avgslope' property of 'st,stm32c0-temp-cal' to required, and
remove its default value, to ensure new series cannot be introduced without
setting the property to the correct value explicitly.
This change does not require any DTSI modification, because there are only
two files using this compatible (stm32f030.dtsi / stm32c0.dtsi), and both
of these already set 'avgslope' explicitly.

Fix the devicetree bindings to actually be used as the default

This requires sadly dropping enums and using #defines for various

These three sensor types are all largely compatible. The SHT21 and
HTU21D can be supported by this driver by sending command 0xE3 instead
of 0xE0 to read the temperature.
Mention the sensor names in bindings and Kconfig to help those looking
for support to find it. There have been at least five PRs attempting to
add SHT21 and/or HTU21D support that did not realize the Si7006 is the
same.
As mentioned in PR #22862, the Sensirion SH21 is the original. The dts
bindings are adjusted (in a backward compatible way!) to make the sht21
the base binding and si7006 is derived from that.
Examples of dts compatibles:
TE Connectivity née Measurement Sepcialties HTU21D:
compatible = "meas,htu21d", "sensirion,sht21";
Sensirion SHT21:
compatible = "sensirion,sht21";
Silicon Labs Si7006

Silicon Labs Si7021
