From 05c823bd327e39586067262c25148cb4888974ab Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Sun, 5 Aug 2012 09:05:33 +0000 Subject: [PATCH] mxs: Clarify why we poweroff in case of brownout in 5v conflict If VDDIO has a brownout, then the VDD5V_GT_VDDIO becomes unreliable but this wasn't clear on code so a comment has been added to clarify it.
