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 Brüns (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 drivers/iio/light/vl6180.c | 126 +++++++++++++++++++++++++-------------------- 1 file changed, 69 insertions(+), 57 deletions(-) -- 2.14.1
