From 4946ff5858392012ed17a079c5b3dd4bc4b15cf9 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 8 Feb 2016 18:01:49 +0100 Subject: [PATCH] iio:ad5064: Use a enum for the register map layout type Currently the ad5064 only supports two different register map variations and this is represented by a bool. This patch changes since to a enum so we can support more variations in the future.
