From 9f72520fa4e0a1c3060c523ca075f323b9c77488 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 19 Oct 2016 19:06:58 +0200 Subject: [PATCH] staging:iio:ad7606: Remove default device configuration from platform data While for some very selected setups it might be useful to be able to provide default configuration data via the platform data, generally this becomes very impractical as the number of configuration options increases. So the general policy is to use the power-on default values of the device and let the application using the device configure it according to its needs. Implement this scheme for the ad7606 driver by removing support for specifying a default configuration via the platform data.
