Subject: [PATCH] CHROMIUM: iio: Add Dyna-Image AP3223 ambient light and proximity driver
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@...a-image.com>
* Templeton Tsai <templeton.tsai@...a-image.com>
* Vic Lee <Vic_Lee@...s.com>
Signed-off-by: Suresh Rajashekara <sureshraj@...gle.com>
