Subject: [PATCH 13/16] iio: hid-sensors: Proximity: Raw read support
Date: Fri, 18 Apr 2014 16:22:33 -0700 [thread overview]
Message-ID: <1397863356-2470-13-git-send-email-srinivas.pandruvada@linux.intel.com> (raw)
In-Reply-To: <1397863356-2470-1-git-send-email-srinivas.pandruvada@linux.intel.com>
Added support for raw reading of channel. If the sensor is powered
off, it will turn on for reading value.
