From 5dd1086142290ea25a67b7a9a48c65cb60636da2 Mon Sep 17 00:00:00 2001 From: Robin Gong Date: Thu, 15 Nov 2012 10:33:41 +0800 Subject: ENGR00233730 PFUZE mx6q_sabresd: remove extra increase for PFUZE tolerance There is no more tolerance issue on PFUZE, it will be only 25mV, so that we no need increase VDDSOC_IN from 1.375V to 1.425V.
