[PATCH v3 0/3] MSM8916: improve gp2ap002 proximity sensor v3

[Christoph Rudorff]

Samsung J5 is equipped with GP2AP002 proximity sensor.
Unfortunally the driver wasn't working, no irq received.

According to datasheet page 8 "Recommended external circuit",
it got tree pins to supply: vio, vdd and vled->leda.

It missed to power up the LED.

I found this looking in downstream kernel, where
several #ifdefs handled the case of 2 or 3 supplies.

Now it works. Tested on samsung-j5:

$ cd /sys/bus/iio/devices/iio\:device1
$ echo 1 > events/in_proximity_thresh_either_en

$ iio_event_monitor /dev/iio\:device1

Event: time: 1791460068846871297, type: proximity, channel: 0,
evtype: thresh, direction: rising

Event: time: 1791460068876669724, type: proximity, channel: 0,
evtype: thresh, direction: falling
