From 8259403183c90572f2b52f46007cf37b462b7701 Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Fri, 14 Sep 2012 12:58:17 +0530 Subject: ARM: DTS: exynos4210-origen: Set LDO3 as always on LDO3 feeds to VDD_11OF power line which drives MIPI, HDMI, SATA, OTG etc. Currently no driver is explicitly using this regulator, hence it gets disabled during boot-time. This leads to system hang when a USB device is attached to the board during system initialization.
