From 000003ea1e2e741def558806bf24e8507792bf56 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Fri, 28 Aug 2020 12:16:23 -0700 Subject: mb/google/zork: Fix active polarity of touchscreen reset GPIO in overridetree v3.6+ of reference schematics have moved to using active low polarity for touchscreen GPIO. This change sets the default polarity in override tree accordingly to active low. To support boards from older builds, variant_touchscreen_update() already updates the polarity to active high.
