Subject: [PATCH v3 0/7] iio: light: vcnl4000: Add features for vncl4040/4200

Add a more complete support for vncl4040 and vcnl4200, which allows to
change the distance of proximity detection and interrupt support for the
illuminance sensor.

Proximity functionality:
  - Interrupt support (new on vcnl4200).

Proximity reduce the amount of interrupts:
  - Adaptable integration time (new on vcnl4200) - the sampling rate
    changes according to this value.
  - Period - interrupt is asserted if the value is above or
    below a certain threshold.

Proximity change the activity distance:
  - Oversampling ratio - Amount of LED pulses per measured raw value.
  - Calibration bias - LED current calibration of the sensor.

Illuminance functionality:
  - Interrupt support.

Illuminance reduce the amount of interrupts:
  - Adaptable integration time - the sampling rate and scale changes
    according to this value.
  - Period – interrupt is asserted if the value is above or
    below a certain threshold.

changes v2:
- [PATCH v2 3/7] Fixed calculation of al_scale.
  Fix the value of vcnl4040 according to the data-sheet.
  Use div_u64 for the division.
scription for the branch

changes v3:
- [PATCH v3 1-3/7] Add differences between the chips as variables in
    chip-spec.
- [PATCH v3 4/7] Changed commit message.
- [PATCH v3 5/7] Use period instead of debounce time. This causes some
  calculations as the period is a time and the chip allows to set a certain
  amount of measurements above/below the threshold, before throwing an
  interrupt.
- [PATCH v3 6/7] Changed commit message.
