From e79e8027c1bb9e5525ad186efef1d89309c378f2 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 19 Oct 2016 19:07:00 +0200 Subject: [PATCH] staging:iio:ad7606: Use oversampling ratio of 1 for no oversampling Currently the ad7606 driver uses a value of 0 for the oversampling ratio to express that no oversampling is done. Strictly speaking this means though that no data capture is done at all. Instead change the driver to use a value of 1, this is in accordance with what other drivers do and what the IIO spec suggests.
