We should probably print what the expected chip-ID is. We already have that information available, based on the device specified via device-tree. Signed-off-by:

These docs are both suffering from being out of date, and from being superceeded by the documentation in Documentation/driver-api/iio Note the inkern.txt drop is left for now as this is an area not well covered by the more recent documentation outside staging. Signed-off-by:

There are no remaining light drivers in staging/iio. The content of this file are either included in the non staging ABI docs, or don't seem to be used in any current driver. Signed-off-by:

These seem to be up to date but never moved out of staging when the driver did. Hence let us move them out now. Signed-off-by:

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. Signed-off-by:

Use the adis managed device functions to setup the buffer and the trigger. The ultimate goal will be to completely drop the non devm version from the lib. Since we are here, drop the `.remove` callback by further using devm functions. Signed-off-by:

The ADC in S3C/S5P/Exynos SoCs can be used also for handling touch screen. In such case the second interrupt is required. This second interrupt can be anyway provided, even without touch screens. This fixes dtbs_check warnings like: arch/arm/boot/dts/s5pv210-aquila.dt.yaml: adc@e1700000: interrupts: [[23], [24]] is too long Signed-off-by:

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. This is part of a bigger cleanup.

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. This is part of a bigger cleanup.

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. This is part of a bigger cleanup.

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). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
