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. changes v4: - [PATCH v3 1-3/7] Fix setting correct als_it for vcnl4040. - [PATCH v3 5/7] Use MICRO macro. Fix values greater than 1 s for the proximity period.
