module will be called atlas-ph-sensor.
iio: chemical: Add support for Bosch BME680 sensor Bosch BME680 is a 4-in-1 sensor with temperature, pressure, humidity and gas sensing capability. It supports both I2C and SPI communication protocol for effective data communication. The device supports two modes: 1. Sleep mode 2. Forced mode The measurements only takes place when forced mode is triggered and a single TPHG cycle is performed by the sensor. The sensor automatically goes to sleep after afterwards. The device has various calibration constants/parameters programmed into devices' non-volatile memory(NVM) during production and can't be altered by the user. These constants are used in the compensation functions to get the required compensated readings along with the raw data. The compensation functions/algorithms are provided by Bosch Sensortec GmbH via their API[1]. As these don't change during the measurement cycle, therefore we read and store them at the probe. The default configs supplied by Bosch are also set at probe. 0-day tested with build success. GSoC-2018: https://summerofcode.withgoogle.com/projects/#6691473790074880 Mentor: Daniel Baluta [1] https://github.com/BoschSensortec/BME680_driver Datasheet: https://ae-bst.resource.bosch.com/media/_tech/media/datasheets/BST-BME680-DS001-00.pdf Note from Jonathan: The compensation functions are 'interesting' and could do with a tidy up in future. However, they work so we can leave that for another day.

Say yes here to build support for Bosch Sensortec BME680 sensor with
temperature, pressure, humidity and gas sensing capability.
This driver can also be built as a module. If so, the module for I2C
would be called bme680_i2c and bme680_spi for SPI support.
