From 12f0323685f4f1357169432d1ca8a75282f2233f Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Mon, 5 May 2014 14:58:29 -0500 Subject: [PATCH] ARM: dts: am335x-evmsk: Add vtt_fixed regulator The VTT regulator for DDR3 termination on the am335x-evmsk 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.
