From 9aee34ecabef065cfec76ce736bedfb1fcf77b03 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 3 May 2013 04:37:07 +0000 Subject: [PATCH] mx23: Fix pad voltage selection bit On mx23 the pad voltage selection bit needs to be always '0', since '1' is a reserved value. For example: Pin 108, EMI_A06 pin voltage selection: 0= 1.8V (mDDR) or 2.5V (DDR1); 1= reserved. Fix the pad voltage definitions for the mx23 case.
