STK3013 is a part manufactured by Sensortek which is marketed as a [1]
"Proximity Sensor". This part is available in several consumer mobile
devices, including, but not limited to, Samsung Galaxy J7 Prime and
Samsung Galaxy A2 Core.

The existing ambient light sensor seemed suitable for this chip, and on
enabling the driver, it was discovered that these "Proximity Sensors" had
ambient light sensing capabilities as well.

The downstream kernel driver shipped with this phone by Samsung [2] exposes
a sysfs interface for proximity sensing, but leaves out the light sensing
features, hence there's no such functionality in userspace.

The following patch series aims to add support for STK3013 as an
ambient light/proximity sensor.

Series LGTM. I'll leave it on list for a few more days though for other
review to come in.

Thanks,

Applied and initially pushed out as testing for 0-day to take a first look at
this.

Thanks,
