Hi, The next 3 patches do the following: - The first patch adds PNI Sensor Corporation to the vendor prefix list. - The second patch adds devicetree binding for RM3100 magnetometer. - The third patch adds the driver for RM3100 magnetometer. -- Song Qiang 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.
