From 45e584850dc7dc617da809e59830c6d2e1eb86b0 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 23 May 2014 02:10:59 +0900 Subject: [PATCH] ARM: dts: enable USB functionality for exynos4210-universal_c210 This patch adds device tree nodes necessary to enable USB support on universalc210 board, this includes UDC controller (USB gadget) as well as EHCI and OHCI host ports. LDO3 and LDO8 regulators are switched to always on mode until EHCI and OHCI drivers will support them correctly.
