Currently, hid sensor als are using the relative hysteresis.
This patch series add the relative hysteresis for hid sensors.

---
v2:
  - (1/3) fix the formatting issue in hid_sensor_read_raw_hyst_rel_value.
  - (3/3) add documentation just for light sensor.

Ye Xiang (3):
  iio: Add relative sensitivity support
  iio: hid-sensor-als: Add relative hysteresis support
  iio: Add relative hysteresis in ABI documentation
