Changes in v5: - Fix a bug about checking if completion is timed out. Used to check if ret < 0. - Add INDIO_BUFFER_TRIGGERED to indio_dev->modes. - Add init mode 'INDIO_DIRECT_MODE'. - Remove case 0 in trigger handler. - store scale value directly instead of store cycle_count_index and search for scale value. - Fix the bug of restarting all channels in rm3100_set_sample_freq. - Replace 4 in rm3100_buffer_preenable with define 'RM3100_CMM_AXIS_SHIFT' - Replace timestamp of trigger_hanlder to use iio_pollfunc_store_time. - Remove rm3100_remove. - Replace 3 seconds timeout time with double conversions time. - Read all 3 axis in case BIT(0) | BIT(2) instead of reading each of them independently. - Remove i2c_check_functionality since regmap_get_i2c_bus already checks it. Changes in v4: - Fix a bug about regmap_range configurations. - Add DRDY trigger support. - Change DRDY interrupt trigger source from RISING to HIGH. - Add a thread function to clear the interrupt. - Change the logic of one-shot read from waiting next continuous ends to writing to POLL register and waiting conversion ends. - Add iio_buffer_setup_ops to enable continuous conversion only when buffer is enabled. - Add active_scan_mask check in continuous conversions. - Remove *wait_measurement() in *trigger_handler(). Changes in v3: - Change PNI to PNI Sensor Corporation in vendor-prefix.txt. - Sort header files in alpabetical order. - Add more specific doc for the mutex. - Fix the bug in the rm3100_set_cycle_count() where we always set the cycle count value to 100 no matter what val is. - Change some multiple else if to switch. - Remove iio_device_release_direct_mode() in the case claim direct mode fails. - Use the same buffer in rm3100_trigger_handler(). - Add space around some operators. - Add manually unwind functions in case devm_add_action() fails. - Move devm_add_action before the devm_iio_device_register(). - Move register defines and rm3100_data struct to *-core.c. - Change some storage variable type of regmap from int to unsigned int. - Change 10e4 to 10^4. - Remove explicit cast of data pointer in rm3100_remove(). - Remve dev in rm3100_data and use regmap_get_device() to obtain device pointer instead. - Change register bits alignment in defines. - Move RM3100_SCAN_BYTES to the top. - Change Channel endieness from LE to BE. - Adjust the place of comment about the 3 second wait time. - Some spell check. Changes in v2: - Add scale channel. - Add EXPORT_SYMBOL_GPL() to export regmap confuguration structures. - Add sampling frequency available attribute. - Clean up headers and License declarations. - Change axis number to 3. - Remove bus specific part in compatible string. - Remove le32_to_cpu(). - Check cycle count registers at *_probe(). - Format comments. - Spell check. - Change prefix from RM_* to RM3100_*. - Check all error return paths. - Add devm_add_action() to avoid race condition when remove.
