This patch series adds support for Sensirion SGP30 and SGPC3 I2C gas sensors. Further product specs available from: https://www.sensirion.com/en/environmental-sensors/gas-sensors/multi-pixel-gas-sensors/ https://www.sensirion.com/en/about-us/links/#c15360 Patch 1/2 add new IIO modifiers used by the driver Patch 2/2 add sgp30/sgpc3 driver and documentation Major changes to v1: * Driver renamed to sgp30 * No or minimal sensor knowledge required to use the device: automatic fixed interval polling (see next point) and initialization. * Background thread for IAQ polling * Remove triggered-buffers support * Add new IIO modifiers for ethanol and H2 * Support for SGPC3 product increment ("feature set 0.6") including humidity compensation and an ultra-low power mode. Unfortunately, the datasheet for this new SGPC3 has not been released yet. * ABI/DT Documentation Many thanks to Peter Meerwald-Standler and Jonathan Cameron for their most valuable feedback on v1.
