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 v4: * Dropped redundant and excessive verbose comments. * Change BMP580 temp IIO return type to IIO_VAL_FRACTIONAL_LOG2 * Dropped loop waiting for NVM operation completion and use regmap_read_poll_timeout instead. * Fix various sizeof calls on NVMEM handling codepath. 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.
