For now we support only the 50% watershed interrupt and start and stop it as part of the buffer bring up. The 75% case may come back in future. Signed-off-by:

Not clearing the stuff_to_read flag can lead to a false flag being set on restarting the buffer if the data was not all read the previous time. The size of the scan is needed to ensure the function iio_buffer_read_first_n_outer actually tries to read the data. This stuff has been broken for some time so not stable material. Signed-off-by:

This was needed when the buffer support was optional. Pointless wrapper now so drop it. Signed-off-by:

In the early days of IIO we were much more inclined to keep the impact of the core IIO elements to the minimum. As time has moved on it has become clear that hardly any builds are done without buffer support and that it adds considerable complexity to the drivers. Hence merge down the buffer and non buffer elements of the sca3000 driver also allowing us to drop the header file used for the interfaces between the two. Signed-off-by:

If attribute/s is/are already enabled (by default or via scripts or manual interaction), issuing -a will fail to enable the channels thereby one has to manually disable the said attribute/s before proceeding with auto-enabling. Add a command-line option -A to force-activate all channels regardless of their current state. Suggested-by:

Use a standard framework to get the reference voltage. It is done that way in the iio subsystem and it will simplify extending of the driver. Structure mcp4725_platform_data is left undeleted because it used in the next patch. This change breaks the current users of the driver, but there is no mainline user of struct mcp4725_platform_data.

Change in handling of the regulator description means that static checkers correctly assume we could be using dereferenced pointer to the regulator. In reality we will never get the -ENODEV error, as current behavior flow does not predict it, because: If the device tree or board file does not define suitable regulators for the component, it will be substituted by a dummy regulator, or, if regulators are disabled altogether, by stubs.

There is a type mismatch between the buffer which is of type s16 and the samples stored, which are declared as __le16. Fix the following sparse warning: drivers/iio/imu/bmi160/bmi160_core.c:411:26: warning: incorrect type in assignment (different base types) drivers/iio/imu/bmi160/bmi160_core.c:411:26: expected signed short [signed] [short] [explicitly-signed] <noident> drivers/iio/imu/bmi160/bmi160_core.c:411:26: got restricted __le16 [addressable] [usertype] sample This is a cosmetic-type patch since it does not alter code behaviour. The le16 is going into a 16bit buf element, and is labelled as IIO_LE in the channel buffer definition. Signed-off-by:

This driver predates the availability of IIO_CHAN_INFO_SAMP_FREQ attribute wherein usage has some advantages like it can be accessed by in-kernel consumers as well as reduces the code size. Therefore, use IIO_CHAN_INFO_SAMP_FREQ to implement the sampling_frequency attribute instead of using IIO_DEVICE_ATTR() macro. Move code from the functions associated with IIO_DEVICE_ATTR() into respective read and write hooks with the mask set to IIO_CHAN_INFO_SAMP_FREQ. Signed-off-by:

Attributes that were once privately defined become standard with time and hence a special global define is used. Hence update driver ad7152 to use IIO_CHAN_INFO_SAMP_FREQ which is a global define instead of IIO_DEV_ATTR_SAMP_FREQ. Move functionality from IIO_DEV_ATTR_SAMP_FREQ attribute into IIO_CHAN_INFO_SAMP_FREQ to implement the sampling_frequency attribute. Modify ad7152_read_raw() and ad7152_write_raw() to allow reading and writing the element as well. Also add a lock in the driver's private data. Signed-off-by:

Recently the kernel has gotten support in the iio subsystem for a number of new accelerometers from mCube, Memsic and MiraMEMS. This commit adds the vendor prefixes already used for these vendors in Documentation/devicetree/bindings/i2c/trivial-devices.txt to vendor-prefixes.txt.

The oversampling ratio is controlled using the oversampling pins, OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control bit. The gpio connected to the OS2 pin is not being set correctly, only OS0 and OS1 pins are being set. Fix the typo to allow proper control of the oversampling pins. Signed-off-by:
