SubjectAdd driver for veml6030 ambient light sensor
Date
The veml6030 is an ambient light sensor from vishay and
is a different hardware from an existing hardware for which
driver currently exist, therefore this driver submission.

* All features; ALS, white channel and power management is
supported.

* All configurable parameters are supported through standard
iio sysfs entries. User space can get valid values of any
parameter (xx_available) and then can write to appropriate
sysfs entry.

* User space can get ALS and White channel readings through RAW
IIO interface.

* IIO events are used to notify application whenever threshold
is crossed. This uses IRQ pin of veml6030.

* Some registers in veml6030 are read only. For these registers
read callback returns error to user space.

There are 2 patches for this submission:
[PATCH 1/2] iio: light: add driver for veml6030 ambient light sensor
[PATCH 2/2] dt-bindings: iio: light: add veml6030 ALS bindings

Regards,
Rishi
