Tomasz Duszynski 7dfc4dc385 dt-bindings: iio: chemical: sps30: update binding with serial example
sps30 has gained support for serial communication so add example to the
binding file. While at it remove reg property from list of required
properties because it's no-op in case of serial communication.

Tomasz Duszynski b2e171f5a5 iio: sps30: add support for serial interface
Sensor has support for both i2c and serial communication interfaces.
Both offer very similar set of features. Minor differences don't impact
overall functionality like doing measurements, etc.

Support for i2c have already been added, this patch adds support
for the latter ie. serial interface.

Jonathan Cameron 101af4c20c iio:ABI docs: Move specific description of out_altvoltageX_frequency to main docs.
The adf4371 has channels that are very closely coupled, so additional
documentation is needed to express these constraints.
Unfortunately having the same sysfs filename in multiple documentation
does not work well when generating automated documentation.
To avoid this issue, we add a new device specific description to the
main docs and remove the one in the device specific file.

Jonathan Cameron cff8431bf4 iio:ABI docs: Fix issue around repeated definition of out_currentY_raw
This one is challenging as both the places this appears in specific drivers
are making 'unusual' uses of what looks like a simple output current
channel.
As a side note, this was particular bit of ABI occurs in other drivers
where the use is much more straight forward e.g. dac/ad5421

This patch attempts to make a best effort of adding it to the main docs but
retaining enough information. Both of these drivers probably need
specific documents being written to describe their unusual interfaces, but
those should be in the main documentation, not under Documentation/ABI.
That is a non trivial job so left for another time.

Jonathan Cameron 69c93a7df7 iio:ABI docs: Fix up duplicate *_calibbias_* documentation for icm42600
This device has the unusual characteristic that the calibbias values
have well defined units (more commonly they are tweaks to a DAC)
Unfortunately the previous approach of having more specific documentation
in sysfs-bus-iio-icm42600 results in warnings during the documentation
build and random ordering in the resulting documentation.

To avoid this, add a note to the main documentation on this special
characteristic for the icm42600.   The _available for calibbias was
missing from the main sysfs-bus-iio docs so also add that, allowing
us to drop the icm42600 specific file.

Typically, in burst mode, the device cannot operate at it's full spi
speed. Hence, the spi transfers for burst mode have to take this into
account. With this change we avoid a potential race with the spi core as

Nuno Sa 00a72db718 iio: adis16475: do not return ints in irq handlers
On an IRQ handler we should not return normal error codes as 'irqreturn_t'
is expected.

This is done by jumping to the 'check_burst32' label where we return
'IRQ_HANDLED'. Note that it is fine to do the burst32 check in this
error path. If we have proper settings to apply burst32, we might just
do the setup now so that the next sample already uses it.

Jonathan Cameron 7bf50a968a iio:adc:ad7476: Handle the different regulators used by various parts.
Not all of the parts supported by this driver use single supply.
Hence we add chip_info fields to say what additional supplies exist
and in the case of vref, ensure that is used for the reference voltage
rather than vcc.

One corner case is the ad7091r which has an internal reference that
can be over-driven by an external reference connected on the vref pin.
To handle that force_ext_vref is introduced and set if an optional
vref regulator is present.

Tested using really simple QEMU model and some fixed regulators.

The devm_add_action_or_reset() callback is changed to take the
regulator as it's parameter so we can use one callback for all the
different regulators without having to store pointers to them in
the iio_priv() structure.

Joe Sandom afa2b78f1e dt-bindings: iio: light: Added AMS tsl2591 device tree binding
Device tree binding for AMS/TAOS tsl2591 ambient light sensor.

This driver supports configuration via device tree and sysfs.
Supported channels for raw infrared light intensity,
raw combined light intensity and illuminance in lux.
The driver additionally supports iio events on lower and
upper thresholds.

This is a very-high sensitivity light-to-digital converter that
transforms light intensity into a digital signal.
