From cd8341b7eb7bcf630a49538684778d87daef3e61 Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Mon, 10 Feb 2014 11:41:49 -0500 Subject: ARM: AM43xx: GP-EVM: Correct GPIO used for VTT regulator control Schematic indicates GPIO5_7 is to be used for VTT regulator control rather than GPIO0_21 so modify enable_vtt_regulator to reflect this. Without this some boards will experience DDR3 corruption and fail to boot.
