Subject: [PATCH v2 0/3] Add relative hysteresis support for hid sensors

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
