From f6e8a9687b785b4c75d71370681f7a6e9fd89685 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Thu, 28 Mar 2013 22:04:00 +0000 Subject: [PATCH] iio: mxs-lradc: Do hardware initialization earlier We need to initialize hardware before registering the touchscreen. Else, we end up setting registers in mxs_lradc_ts_open(), getting called just after registering the touchscreen with input_register_device() and by the end of mxs_lradc_probe(), we reset the LRADC block hence losing the correct configuration.
