Subject: [PATCH v3 3/4] staging: iio: ad7816: Set RD/WR pin and CONVST pin as outputs.
Date: Fri, 9 Nov 2018 13:07:18 +0530	[thread overview]
Message-ID: <fbc5a97bc44a0c57ba21f375ccec888f5113d702.1541733949.git.nishadkamdar@gmail.com> (raw)
In-Reply-To: <cover.1541733949.git.nishadkamdar@gmail.com>

The RD/WR pin and CONVST pin are logical inputs to the AD78xx
chip as per the datasheet. Hence convert them to outputs.
