This prevents use of this driver with ACPI via PRP0001 and is
an example of an anti pattern I'm trying to remove from IIO.
Hence drop from this driver.

This enables use of ACPI PRP0001 and removes an antipattern I am
trying to stop people copying in IIO.
This particular case is more complex than most because it allowed
probing via sysfs with out a fwnode but would presumably always
have then failed. Now the code will assume that properties are
the defaults if not specified or the firmware node is not present.
This relaxation of the constraints should not break any existing
cases and may enable some new ones.

These result in a very small reduction in driver size, but at the
cost of more complex build and slightly harder to read code.
In the case of of_match_ptr it also prevents use of PRP0001
ACPI based identification. In this particular case we have
a valid ACPI/PNP ID that I am assuming was issued by Analog
Devices. That should be used in preference to PRP0001 but doesn't
mean we should prevent that route.

Currently the iio_buffer_{alloc,free}_sysfs_and_mask() take 'indio_dev' as
primary argument. This change splits the main logic into a private function
that takes an IIO buffer as primary argument.
That way, the functions can be extended to configure the sysfs for multiple
buffers.

Whilst there is some useful info in here, it can be easily
obtained from datasheets. Some of the info should perhaps
be incorporated into a device tree bindings doc.
As this didn't move out of staging with the driver, I'm suggesting
we just drop it. We don't generally carry per driver documentation
with the exception of non standard ABI which is not the case here.

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

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.

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.

There seems no reason to allow for compile-testing on ARM only, so
remove this restriction.
Build-tested with allyesconfig on x86.
