[PATCH] CHROMIUM: iio: Add Dyna-Image AP3223 ambient light and proximity driver
From: Suresh Rajashekara
Date: Mon Sep 28 2015 - 03:30:22 EST
Minimal implementation. This is based on the driver provided by
the vendor (which wasn't in the IIO framework). Authors of the
driver from the vendor included
* John Huang <john.huang@xxxxxxxxxxxxxx>
* Templeton Tsai <templeton.tsai@xxxxxxxxxxxxxx>
* Vic Lee <Vic_Lee@xxxxxxxx>
Signed-off-by: Suresh Rajashekara <sureshraj@xxxxxxxxxx>
