Subject[PATCH] iio: light: acpi-als: Report data as processed rather than raw
Date
As per the ACPI specification (Revision 5.0) [1], the data coming
from the sensor represent the ambient light illuminance reading
expressed in lux. Use IIO_CHAN_INFO_PROCESSED instead of
IIO_CHAN_INFO_RAW to signify that the data are pre-processed.
