Subject: [PATCH v3 0/3] Add LTRF216A Driver

This patchset adds support for ltrf216a Ambient Light Sensor
and documents the DT bindings for the same.


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.
