+Subject: Revert "iio: hi8435: cleanup reset gpio"
+
+From: Jonathan Cameron <jic23@kernel.org>
+
+commit e18788afebd12a53b3e173d5b1390a785346da2e upstream.
+
+This reverts commit 61305664a542f874283f74bf0b27ddb31f5045d7.
+
+This commit was applied prematurely and will break some existing
+situations where the signal is inverted as part of voltage level
+conversions.
