These prevent use of this driver with ACPI via PRP0001 and are an example of an anti pattern I'm trying to remove from IIO. Hence drop them from this driver. Also switch to device_get_match_data() from of_ variant and adjust headers to reflect the change. Signed-off-by:

Given that an ACPI binding must start with 3 or 4 capitals, this cannot represent a valid binding. It seems unlikely anything out there is using it. Signed-off-by:

Whilst this driver has an ACPI binding, it is not of a form that is valid under ACPI so will be dropped shortly. Also switch to device_get_match_data() and switch headers. Signed-off-by:

I'd like to be enable W=1 for all IIO builds as it catches real issues as well as more minor documentation issues such as this (also good to fix though!) drivers/iio/imu/adis16400.c:183: warning: Function parameter or member 'avail_scan_mask' not described in 'adis16400_state' Signed-off-by:

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. Signed-off-by:

Use only one line for the closing bracket of the last entry and the opening bracket for the next one to keep the style across the whole array consistent. Also add a "sentinel" comment to the last entry and remove the comma to ensure that there won't be any entry after it. No functional changes. 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These docs are both suffering from being out of date, and from being superceeded by the documentation in Documentation/driver-api/iio Note the inkern.txt drop is left for now as this is an area not well covered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:

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:

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.

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:
