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.
