From e3c62b422bb90401253a1472d7aab8816102d570 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 9 Sep 2014 15:40:52 +0200 Subject: [PATCH 3/6] ARM: dts: rockchip: enable usb ports on Radxa Rock This enables both the otg and host port and adds the vbus regulators on the Radxa Rock board. As we don't have phy support yet, the vbus regulators are added in always-on mode.
