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.
