2019-10-22iio: pressure: bmp280: use devm action and remove labels from probeBartosz Golaszewski
We can drop some duplicate code if we use devm_action for disabling regulators and pm and the managed variant of iio_device_register(). This allows us to completely remove all remove() callbacks from both i2c and spi code.

2016-07-03iio: pressure: bmp280: add power managementLinus Walleij
The PM280 has an internal standby-mode, but to really save power we should shut the sensor down and disconnect the power. With the proper .pm hooks we can enable both runtime and system power management of the sensor. We use the *force callbacks from the system PM hooks. When the sensor comes back we always reconfigure it to make sure it is ready to roll as expected.

2016-07-03iio: pressure: bmp280: add support for BMP085 EOC interruptLinus Walleij
The first version of this sensor, BMP085, supports sending an End-of-Conversion (EOC) interrupt. Add code to support this using a completion, in a similar vein as drivers/misc/bmp085.c does. Make sure to check that we are given a rising edge, because the EOC line goes from low-to-high when the conversion is ready.

2016-07-03iio: pressure: bmp280: add SPI interface driverLinus Walleij
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.
