Changes in v6 - Fix some errors reported by kernel test robot. - Add protocol details for the datasheet link. - Remove useless assignments. - Add unit details for read data delay macro. - Use pm_sleep_ptr(). Changes in v5 - Add power management support. - Add reset functionality. - Use readx_poll_timeout() to get data. - Cleanup some of the redundant code. - Update int_time_fac after I2C write is successful. - Rename mutex to lock. - Use Reverse Xmas tree pattern for all variable definitions. - Improve error handling messages and add error codes. - Add one more MODULE_AUTHOR. - Remove cleardata which was reading data for infrared light. - Remove patch for deprecated vendor prefix [PATCH v4 3/3]. - Remove deprecated string from DT binding document. Changes in v4 - Add more descriptive comment for mutex lock - Fix mutex locking in read_raw() - Use i2c_smbus_read_i2c_block_data() Changes in v3 - Use u16 instead of u8 for int_time_fac - Reorder headers in ltrf216a.c file - Remove int_time_mapping table and use int_time_available - Fix indentation in the bindings file. Changes in v2 - Add support for 25ms and 50ms integration time. - Rename some of the macros as per names given in datasheet - Add a comment for the mutex lock - Use read_avail callback instead of attributes and set the appropriate _available bit. - Use FIELD_PREP() at appropriate places. - Add a constant lookup table for integration time and reg val - Use BIT() macro for magic numbers. - Improve error handling at few places. - Use get_unaligned_le24() and div_u64() - Use probe_new() callback and devm functions - Return errors in probe using dev_err_probe() - Use DEFINE_SIMPLE_DEV_PM_OPS() - Correct the formula for lux to use 0.45 instead of 0.8 - Add interrupt and power supply property in DT bindings - Add vendor prefix name as per the alphabetical order.
