Subject: [PATCH v3 0/7] Add support for pressure sensor Bosch BMP580
This patchset adds support for the new pressure sensors BMP580 extending
the bmp280 driver.
Patch 1 introduces a minor refactor of the driver structure to change how
the device matching and driver initialization is performed. In place of
the chips ids, the driver_data now contains a pointer to its chip_info.
To perform this change, a series of declarations previously on the core
file were migrated to the shared header file, to allow access to specific
fields on the chip_info on the I2C and SPI drivers. This change is
required because BMP380 and BMP580 have the same chip_id and values would
collide using the chip_id as the driver_data value.
Patch 2 introduces new preinit callback and unifies init logic across all
supported variants.
Patch 3 made calibration callback function optional.
Patch 4 deletes misleading i2c reference on bmp280 Kconfig entry.
Patch 5 extends the bmp280 driver with the new logic to read measurements
and configure the operation parameters for the BMP580 sensors.
Patch 6 updates the devicetree binding docs with the new sensor id.
Patch 7 adds the NVMEM operations to read and program the NVM user range
contained in the non-volatile memory of the BMP580 sensors.
Changes in v3:
* Refactor driver structure to use chip_info structs as driver_data and
updated i2c and spi implementations device match codepaths.
* Deleted Kconfig driver title misleading i2c reference.
* Made calibration reading optional as a prerequisite patch in preparation
for the bmp580 built in compensation.
* Break command helper function in soft-reset helper function and NVM
operation helper.
* Fixed minor styling issues thorough patches.
Changes in v2:
* For patch 3, fixed missing retcodes reported by the kernel test robot.
* For patch 5, fixed logic paths that left the sensor mutex locked
reported by the kernel test robot.
