From f3ea181d9833c17a7477b48d00083d5602c01cb4 Mon Sep 17 00:00:00 2001 From: Lijian Zhao Date: Wed, 17 Apr 2019 11:21:17 -0700 Subject: mb/google/sarien: Update GPIO GPP_C23 setting GPIO pin GPP_C23 is used as level trigger but not edge trigger, also it is not inverted, correct it here. According to board schematic, GPP_C23 connected with 3.3v pull up, so the pin is low active. BUG=b:128554235 TEST=Boot up arcada platform with stylus keep on touching the screen, the touch screen is still functional once in OS stage. Without change, touch screen is not functional at same scenario.
