iio: pressure: Add driver for Honeywell ABP family

2016-10-01T14:14:37Z

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).

iio: pressure: bmp280: add SPI interface driver

2016-07-03T10:27:15Z

This patch mimics the SPI functionality found in the misc driver in drivers/misc/bh085-spi.c to make it possible to reuse the existing BMP280/BMP180/BMP085 driver with all clients of the other driver. The adoption is straight-forward since like the other driver, it is a simple matter of using regmap. This driver is also so obviously inspired/copied from the old misc driver in drivers/misc/bmp085.c that I just took the liberty to add in the authors of the other drivers + self in the core driver file. The MISC driver also supports a variant named "BMP181" so include that here to be complete in comparison to the old driver. The bus mapping code for SPI was written by Akinobu Mita.

iio: pressure: bmp280: split off an I2C Kconfig entry

2016-07-03T10:27:14Z

This creates a separate BMP280_I2C Kconfig entry that gets selected by BMP280 for I2C transport. As we currently only support I2C transport there is not much practical change other than getting a separate object file (or module) for the I2C driver part. The old Kconfig symbol BMP280 will still select the stuff we need so that oldconfig and old defconfigs works fine.

iio: pressure: bmp280: split driver in logical parts

2016-07-03T10:27:11Z

This splits the BMP280 driver in three logical parts: the core driver bmp280-core that only operated on a struct device * and a struct regmap *, the regmap driver bmp280-regmap that can be shared between I2C and other transports and the I2C module driver bmp280-i2c. Cleverly bake all functionality into a single object bmp280.o so that we still get the same module binary built for the device in the end, without any fuzz exporting symbols to the left and right.

iio: pressure: mpl115: support MPL115A1

2016-01-30T16:27:12Z

mpl115 driver currently supports i2c interface (MPL115A2). There is also SPI version (MPL115A1). The difference between them is only physical transport so we can easily support both while sharing most of the code. Split the driver into a core support module and one module each for I2C and SPI support.
