From f1c8547f56f1da9db51fe3281479c823e949a9fd Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 9 Sep 2014 15:40:52 +0200 Subject: [PATCH] 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.
