ebf0aa3ed1 dt-bindings: iio: accel: adxl345: add interrupt-names 
Add interrupt-names INT1 and INT2 for the two interrupt lines of the
sensor.

When one of the two interrupt lines is connected, the interrupt as its
interrupt-name, need to be declared in the devicetree. The driver then
configures the sensor to indicate its events on either INT1 or INT2.

If no interrupt is configured, then no interrupt-name should be
configured, and vice versa. In this case the sensor runs in FIFO BYPASS
mode. This allows sensor measurements, but none of the sensor events.

ec2253b064 iio: adc: rockchip: correct alignment of timestamp 
I assume this device is only used on architectures where a 8 byte
integer type is always 8 byte aligned.  However, I would prefer IIO
drivers to never make that assumption as the code gets copied into
new drivers which are not so tightly couple to one driver and those
can run on architectures that align these types to only 4 bytes in which
case this structure may be 4 byte to small leading to a buffer overrun.

af6aca656a iio: dac: Support ROHM BD79703 DAC 
The ROHM BD79703 is a 6 channel digital to analog converter.

Based on the data-sheet examples the hardware would support setting the
DAC word without changing the actual output. The data-sheet is not too
specific on how the enabling the output of new voltage set by DAC
should be done - hence this is not implemented by the driver.

The BD79703 would also support two specific "PULL_DOWN" modes. These
aren't currently supported by the driver either.

Add a very basic support for controlling the channel outputs one-by-one.

84b6b55584 iio: dac: ad7293: enable power before reset 
Change the order of regulator enable and reset so that power supplies
are turned on before touching the reset line. Generally, chips should
have the VDRIVE supply enabled before applying voltage on any pins.

While we are at it, remove the voltage level checks. If the power
supplies are not supplying the correct voltage, this is a hardware
design problem, not a software problem.

6ade82946f iio: ABI: use Y consistently as channel number 
Change X to Y when referring to channel number in the ABI documentation.
There were only a few cases using X (and one using Z). By far, most
documented attributes are using Y for the channel number placeholder.
For consistency, we should follow the same convention throughout.

The ad7173 family of chips has up to four calibration modes.

Internal zero scale: removes ADC core offset errors.
Internal full scale: removes ADC core gain errors.
System zero scale: reduces offset error to the order of channel noise.
System full scale: reduces gain error to the order of channel noise.

All voltage channels will undergo an internal zero/full scale
calibration at bootup.

System zero/full scale can be done after bootup using the newly created
iio interface 'sys_calibration' and 'sys_calibration_mode'

c3948d0900 iio: adc: ad4000: Add support for PulSAR devices 
The ADI PulSAR series of single-channel devices comprises differential and
pseudo-differential ADCs that don't require any input data from the host
controller. By not requiring a data input line, PulSAR devices can operate
with a 3-wire only data bus in some setups.

The AD4000 series and the single-channel PulSAR series of devices have
similar SPI transfer specifications and wiring configurations.
Single-channel PulSAR devices are slower than AD4000 and don't have a
configuration register. That taken into account, single-channel PulSARs can
be supported by the ad4000 driver without any increase in code complexity.

Extend the AD4000 driver to also support single-channel PulSAR devices.
