From 8c125f5f325e5caf171f6af95b7cfe7f3e3ba78b Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Sun, 10 Jan 2021 00:11:44 +0100 Subject: iio:pressure:ms5637: introduce hardware differentiation Some sensors in the ms58xx family have a different PROM length and a different number of available resolution. introduce struct ms_tp_hw_data to handle those differences.
