This patch series adds support for Texas Instruments OPT4060 RGBW Color sensor
using the i2c interface.

The driver exposes both raw adc values and calculated lux values though sysfs.
Integration time can be configured though sysfs as well. The OPT4060 sensor
supports both rising and falling threshold interrupts. These interrupts are
exposed as IIO events. The driver also implements an IIO triggered buffer with
two triggers, one trigger for conversion ready interrupts and one trigger for
threshold interrupts. The typical use case for this is to define a threshold and
listen for the events, and at the same time enable the triggered buffer with the
threshold trigger. Once the application gets the threshold event, the values
from the time of the event will be available in the triggered buffer. This
limits the number of interrupts between sensor and host and also the the usage
of sysfs for reading values after events.
