From 6aeed16422df88c697d034ed4688ab44e41fa070 Mon Sep 17 00:00:00 2001 From: Bora Guvendik Date: Fri, 27 Sep 2019 22:26:49 -0700 Subject: [PATCH] mb/google/drallion: Adjust GPD3 pin termination Internal pull up need to be enabled for GPD3 as power button pin for PCH according cometlake pch EDS vol1 section 17-1. Without that pin will stay floating and hook up XDP can cause system shutdown as power buttone event will trigger. BUG=N/A TEST=Hook up XDP on drallion platform, able to boot up into OS and stay at power up state.
