From 9f310dedfecdf53974e6e7c21d8d4dc7e8ab8c14 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 1 Jul 2013 15:07:05 -0600 Subject: ARM: tegra: fix VBUS regulator GPIO polarity in DT Commit 4c94c8b "ARM: tegra: update device trees for USB binding rework" added regulator definitions for GPIO-controlled USB VBUS. However, none of these contained the essential DT property enable-active-high. Add this so that the regulator definitions are correct.
