This patchset adds BMP380 variant to the already existing drivers for the Bosch BMP180/280 pressure sensors. Patch 1 adds references and sensor id to the devicetree bindings docs. Patch 2 adds references to the new sensors on the Kconfig file. Patch 3 is a minor refactoring simplifying driver initialization logic to facilitate the integration of the new sensor variant extending the information stored in the "chip_info" struct. Patch 4 adds the basic logic to initialize and read measurements from the sensor Patch 5 adds advanced configurable features such as sampling frequency and IIR filter through the sysfs API Changes in v2: - Added patch 2 updating Kconfig with references to new sensor - Patch 3 adds changes proposed by Jonathan Cameron <jic23@xxxxxxxxxx> to declutter and unify configuration logic for the different sensors extending "chip_info" struct with default configuration parameters. - Patch 4: store temperature and pressure adc values on 3 byte array instead of using the type __le32. Uses function get_unaligned_le24 to convert the little-endian encoded 3 byte value to an integer. - Patch 4: drops custom macro le16_from_bytes and use get_unaligned_le16 - Patch 4: generate masks using GENMASK macro. - Patch 4: use FIELD_PREP to generate bitfields for registries - Patch 4: dropped stray formatting change. - Patch 5: adds sanity checks in bmp280_read_raw for channel properties only available in the BMP380. - Patch 5: on bmp280_write_* checks if a problem ocurred committing new configuration and tries to restore previous working configuration to keep the sensor in a previous working state. - Patch 5: refactored bmp380_chip_config to only check for configuration errors when a configuration change is detected. - Patch 5: improved invalid configuration detection on BMP380 restarting measurement loop to force a new measurement after the configuration is updated.
