2020-09-21iio: adc: fsl-imx25-gcq: Replace indio_dev->mlock with own device lockSergiu Cuciurean
As part of the general cleanup of indio_dev->mlock, this change replaces it with a local lock, to protect against any other accesses during the reading of sample. Reading a sample requires multiple consecutive regmap operations and a completion callback, so this requires that no other read occurs until it completes. This is part of a bigger cleanup.

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.

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. Drop them to remove this restriction. Also switch of.h for mod_devicetable.h include given use of struct of_device_id which is defined in that header.

2020-09-17iio:imu:adis16400: Sort out missing kernel doc.Jonathan Cameron
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: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Cc: Alexandru Ardelean <alexandru.ardelean@analog.com> Link: https://lore.kernel.org/r/20200913132115.800131-2-jic23@kernel.org
2020-09-17iio: buffer: split buffer sysfs creation to take buffer as primary argAlexandru Ardelean
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.

2020-09-16iio: adc: meson-saradc: Make the of_device_id array style consistentMartin Blumenstingl
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.

The proper error code should be ENODEV (vs EINVAL) in case the chip ID isn't recognized.

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

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.
