Subject: [PATCH v1 0/2] Support for Avago APDS9306 Ambient Light Sensor
This series adds support for Avago (Broadcom) APDS9306 Ambient Light
Sensor.
Datasheet: https://docs.broadcom.com/doc/AV02-4755EN
Following features are supported:
- I2C interface
- 2 channels - als and clear
- Raw data for als and clear channels
- Up to 20 bit resolution
- 20 bit data register for each channel
- Common Configurable items for both channels
- Integration Time
- Scale
- High and Low threshold interrupts for each channel
- Selection of interrupt channels - als or clear
- Selection of interrupt mode - threshold or adaptive
- Level selection for adaptive threshold interrupts
- Persistence (Period) level selection for interrupts
This driver also uses the IIO GTS Helpers Namespace for Scales, Gains
and Integration time implementation.

v0 -> v1
- dt_bindings
- Squashed apds9300 and apds9600 dt bindings, added apds9306 bindings on
top of that
- Added detailed commit message for dt_bindings
- apds9306 driver
- Fixes as per review
- Not disabling the regmap internal lock
- Removing processed attribute for als channel which exposes raw values
- Modified the iio gts scale implementation for above change
- Not implementing a fallback and warning for compatibility and part ID
mismatch as suggested by Matti and Jonathan as Rob insisted on having
a single compatible string for the driver (if the device can power up
with a single compatible string, which it does).
