Replace sprintf() with sysfs_emit() in sysfs attribute show callbacks. sysfs_emit() is the preferred API as it is aware of the sysfs buffer page size limit. Signed-off-by: Gabriel Rondon <grondon@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
Fix a typo in the ADXL380_PART_ID_REG macro name where it was incorrectly defined as ADLX380_PART_ID_REG. Also update its usage in adxl380_setup(). Signed-off-by: Nikhil Gautam <nikhilgtr@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Temperature was wrongly represented as 12-bit signed, confirmed by checking the datasheet. Even if the temperature is negative, the value in the register stays unsigned.

Add support for the Analog Devices ADXL371, a +-200g 3-axis MEMS accelerometer sharing the same register map as the ADXL372 but with different ODR values (320/640/1280/2560/5120 Hz vs 400/800/1600/3200/ 6400 Hz), different bandwidth values, and different timer scale factors for activity/inactivity detection. Due to a silicon anomaly (er001) causing FIFO data misalignment on all current ADXL371 silicon, FIFO and triggered buffer support is disabled for the ADXL371 - only direct mode reads are supported.

Extract the triggered buffer, trigger allocation, and IRQ request logic from adxl372_probe() into a dedicated adxl372_buffer_setup() helper. This reduces the probe function complexity and prepares for conditionally disabling buffer support on device variants with known FIFO issues. No functional change intended.

Introduce a chip_info structure to parameterize device-specific properties such as ODR/bandwidth frequency tables, activity/inactivity timer scale factors, and the maximum ODR value. This refactors the driver to use chip_info lookups instead of hardcoded values, preparing the driver to support multiple device variants. The sampling_frequency and filter_low_pass_3db_frequency available attributes are switched from custom sysfs callbacks to read_avail() based handling via info_mask_shared_by_type_available. This enforces consistent formatting through the IIO framework and makes the values accessible to in-kernel consumers. The SPI/I2C probe functions are updated to pass a chip_info pointer instead of a device name string. No functional change intended.

Replace manual mutex_lock/mutex_unlock pair with guard(mutex) in adxl372_write_threshold_value(). This ensures the mutex is released on all return paths and allows returning directly without a goto label.
