Subject[PATCH v2 0/5] Add support for pressure sensor Bosch BMP380
Date
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@kernel.org>
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.
