From 5d27f40418973ac09b0aa5d6289648f9b77b4952 Mon Sep 17 00:00:00 2001 From: Tim Chen Date: Thu, 12 Apr 2018 07:39:40 +0000 Subject: Revert "mb/google/reef: Override USB2 phy settings" This reverts commit 70ba1b7e78930acca578114cdadcbcec367730e8. This commit can only pass far-end USB eye diagram but will fail on near-end. Confirmed with Intel we should revert it.
