Subject: [PATCH 1/3] iio: proximity: as3935: correct IIO_CHAN_INFO_RAW output
Date: Sat, 21 May 2016 20:01:01 -0700	[thread overview]
Message-ID: <1463886063-20004-2-git-send-email-mranostay@gmail.com> (raw)
In-Reply-To: <1463886063-20004-1-git-send-email-mranostay@gmail.com>

IIO_CHAN_INFO_RAW was returning processed data which was incorrect.
This also adds the IIO_CHAN_INFO_SCALE value to convert to a processed value.
