Device tree binding for AMS/TAOS tsl2591 ambient light sensor. This driver supports configuration via device tree and sysfs. Supported channels for raw infrared light intensity, raw combined light intensity and illuminance in lux. The driver additionally supports iio events on lower and upper thresholds. This is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal. Datasheet Available at: https://ams.com/tsl25911 Signed-off-by: Joe Sandom <joe.g.sandom@xxxxxxxxx> --- Changes in v4: - Corrected id field to include vendor name in prefix Notes: - Previously incorrectly included binding in same patch as driver. This was pointed out by the maintainer and has now been changed to a patch series.
