2016-10-23iio: dac: mcp4725: use regulator frameworkTomas Novotny
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.

2016-10-23iio: ms65611_core: Fixes dereferencing regulator pointerCrt Mori
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.

2016-10-01iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8William Breathitt Gray
The ACCES 104-QUAD-8 is a general purpose quadrature encoder counter/interface board. The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter.

2016-10-01iio: pressure: Add driver for Honeywell ABP familyMarcin Malagowski
This patch adds minimal driver for the Honeywell Amplified Basic Pressure sensors series. Sensors are pretty simple but are available in many variants: - psi/mbar/kPa output, - analog/i2c/spi, - gage/differential measurement, - different measure ranges etc. Refer to datasheets for more details: http://sensing.honeywell.com/honeywell-sensing-basic-board-mount-pressure-sensors-abp-series-datasheet-323005128-c-en.pdf http://sensing.honeywell.com/index.php%3Fci_id%3D45841 Driver internals: - i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c bus doesn't support it, it is required to send a dummy byte to trigger measurement, - since iio sysfs expects kilopascals, mbar-variants are treated as their respective kPa-s, hence i2c id-table has doubled entries in one line: { "abp060mg", ABP006KG }, { "abp006kg", ABP006KG }, - psi-variants have prescaled values in config, - no temperature reads yet. Work remained: - optional temperature channel, - SPI support, - DT binding. Changes since v1: - mutex is now locked in read_raw(), - corrected error codes, - fixed coding style issues, - renamed few defines and functions abp -> abp060mg (some structs left as they were to keep the sensible meaning).

2016-09-27iio:adc: Add support for AD7766/AD7767Lars-Peter Clausen
Add support for the AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1, AD7767-2 Analog to Digital converters. It's a family of single channel 24-bit SAR ADCs. They are all digital interface compatible and the main difference is the internal decimation rate and analog performance. For communication with the host processor a SPI interface is used. In addition the part has a data ready pin that is pulsed for one MCLK cycle when a conversion has completed and can be used as a IIO trigger.

2016-09-27iio:max1027: Use iio_trigger_validate_own_device() helperLars-Peter Clausen
Use the new iio_trigger_validate_own_device() to verify that the trigger can only be attached to the matching IIO device rather than using a custom variant. While the implementation of iio_trigger_validate_own_device() and the custom variant and are not identical their behaviour is.
