[PATCH v3 0/4] Currently, the vl6180 driver reports bogus in_illuminance_scale values

From: Stefan BrÃns
Date: Sun Sep 24 2017 - 18:01:06 EST


when the integration time or hardware gain are changed from its default
value, i.e. it always reports a fixed value.

To avoid readback of the register values in case integration time, gain
or scale is queried, save the register values. Use the saved values
to report the correct scale value.

Changes in v3:
- Drop whitespace change
- Use IIO_VAL_FRACTIONAL for integration time return value

Changes in v2:
- Removed redundant parenthesis
- Add missing spaces

Stefan BrÃns (4):
iio: light: vl6180: Move range check to integration time setter,
cleanup
iio: light: vl6180: Avoid readback of integration time register
iio: light: vl6180: Cleanup als_gain lookup, avoid register readback
iio: light: vl6180: Correct ALS scale for non-default gain/integration
time
