Subject: [PATCH v3 0/3] iio: humidity: hdc3020: add threshold events support

Based on Fix:
a69eeaad093d "iio: humidity: hdc3020: fix temperature offset" in branch
fixes-togreg

Changes in V2:
  - Fix alphabetical order of includes(Christophe)
  - Fix typo: change varibale name "HDC3020_R_R_RH_THRESH_LOW_CLR" to
    HDC3020_R_T_RH_THRESH_LOW_CLR to match variable name pattern(Christophe)
  - Add constants HDC3020_MIN_TEMP and HDC3020_MAX_TEMP for min/max threshold
    inputs (Christophe)
  - Change HDC3020_MIN_TEMP to -40, as stated in the datasheet(Javier)

Changes in V3:
  - drop u8 register pairs and switch to 16bit defines(Jonathan)
  - create helper functions to avoid code duplication(Jonathan)
  - Add interrupt bindings in example
  - use the decimal part for setting thresholds(Javier)
  - use return in switch cases hdc3020_read_thresh(Jonathan)
  - fix interrupt handler:(Jonathan)
    - return IRQ_HANDLED when we get a read back failure
    - take the timestamp into a local variable
  - fix multiline comments(Jonathan)
  - use fixed value "hdc3020" instead of dev_id in probe
  - clear interrupt after registering the interrupt handler
  - remove interrupt polarity
