From b2873bfa7b5d5c3e6ab3e318d910c7dd707706cb Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Mon, 5 May 2014 14:58:28 -0500 Subject: [PATCH] ARM: dts: am437x-gp-evm: Add vtt_fixed regulator The VTT regulator for DDR3 termination on the am437x-gp-evm is controlled by a gpio. It is configured by the bootloader so here we define an always-on, fixed voltage regulator to hold the gpio.
