makes sense to cleanup the code a bit, to prevent it from being used as an

This change moves the lock only where it is explicitly needed to protect
resources from potential concurrent accesses.
It also reworks the switch statements to do direct returns vs caching the
return value on a variable.

Conversion from txt to yaml. The binding documents that
as not all boards will make use of the ADC channels via a consumer
driver. It does no harm however, so we will leave it as required.

iio: frequency: adf4350: Replace indio_dev->mlock with own device lock
As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock.
The lock protect the state of the device from potential concurrent writes.
The device is configured via a sequence of SPI writes, and this lock is
meant to prevent the start of another sequence before another one has
finished.
iio: dac: ti-dac7612: Replace indio_dev->mlock with own device lock
As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock on the device's state from potential concurrent write
accesses from userspace. The write operation requires an SPI write, then
toggling of a GPIO, so the lock aims to protect the sanity of the entire
sequence of operation.
iio: stm32-dac: Replace indio_dev->mlock with own device lock
As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock. The lock protects against potential races when
reading the CR reg and then updating, so that the state of pm_runtime
is consistent between the two operations.
Provide a way for continuous data capture by setting up buffer support. The
data ready signal exposed at the SYNC pin of the ADXRS290 is exploited as
a hardware interrupt which triggers to fill the buffer.
Triggered buffer setup was tested with both hardware trigger (DATA_RDY) and
software triggers (sysfs-trig & hrtimer).
iio: gyro: adxrs290: use hook for devm resource unwinding
Make use of devm_add_action_or_reset() hook to switch device into STANDBY
mode during standard resource unwinding. The patch includes a helper
function, in the form of adxrs290_set_mode(), to realise driving the
device into STANDBY mode.

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: temperature: mlx90632: Interface to change object ambient temperature
Since object temperature might be different than the sensor temperature
the infrared sensors should provide an interface to inject ambient
temperature. This was in past done via write to ambient temperature
interface (in_temp_ambient_raw), but I think most people did not know
about it. This solution introduces a new iio type of the CALIBAMBIENT
which is hopefully more descriptive and more explicit about the purpose
and capabilities of the sensors.

iio: sx9310: Prefer async probe
On one board I found that:
probe of 5-0028 returned 1 after 259547 usecs
While some of this time is attributable to the pile of i2c transfers
that we do at probe time, the lion's share (over 200 ms) is sitting
waiting in the polling loop in sx9310_init_compensation() waiting for
the hardware to indicate that it's done.
There's no reason to block probe of all other devices on our probe.
Turn on async probe.

iio: accel: bma220: Drop ACPI_PTR() and accompanying ifdeffery
The driver is quite likely used only on ACPI based platforms and
rarely build with CONFIG_ACPI=n. Even though, the few dozens of bytes
is better than ugly ifdeffery and inclusion of heavy header.
As a result, replace acpi.h with mod_devicetable.h.
Drops the deprecated compatibles without the vendor name.
Whilst the driver continues to support these for old dt blobs,
any dt bindings that are actuallly verified against this document should
be fixed to add the vendor name.
Added the #io-channel-cells property to allow for consumers.
