* iio:pressure: initial zpa2326 barometer supportGregor Boirie2016-09-181-0/+3
| | | | | | | | Introduce driver for Murata ZPA2326 pressure and temperature sensor: http://www.murata.com/en-us/products/productdetail?partno=ZPA2326-0311A-R Signed-off-by: Gregor Boirie <gregor.boirie@parrot.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio: pressure: bmp280: add SPI interface driverLinus Walleij2016-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 entryLinus Walleij2016-07-031-1/+2
| | | | | | | | | | | | | 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 partsLinus Walleij2016-07-031-0/+1
| | | | | | | | | | | | | | 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 MPL115A1Akinobu Mita2016-01-301-0/+2
| | | | | | | | | | | | | | | | | | 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.

* iio: Add a comment to about alphabetical order to Kconfigs and MakefilesLars-Peter Clausen2013-08-031-0/+1
| | | | | | | | | | | | Keeping Makefile and Kconfig entries in alphabetical order usually works better than just appending new entries at the end, since it reduces the amount of conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to document that the entries should be kept in alphabetical order. Also reorder those entries which weren't in alphabetical order yet.
