This patchset adds support for the new pressure sensors BMP580 extending the bmp280 driver. Patch 1 introduces a variant enumeration and refactors sensor verification logic adding a chip_id field to the chip_info struct. 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 extends the bmp280 driver with the new logic to read measurements and configure the operation parameters for the BMP580 sensors. Patch 4 updates the devicetree binding docs with the new sensor id. Patch 5 adds the NVMEM operations to read and program the NVM user range contained in the non-volatile memory of the BMP580 sensors. 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.
