From mboxrd@z Thu Jan 1 00:00:00 1970 From: wxt@rock-chips.com (Caesar Wang) Date: Thu, 7 Jul 2016 12:46:40 +0800 Subject: [PATCH] arm64: dts: rockchip: support the usb2phy for rk3399 evb Message-ID: <1467866800-24794-1-git-send-email-wxt@rock-chips.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Frank Wang This patch adds the usb2phy needed dts node information for rk3399. USB2.0 PHY is comprised of one Host port and one OTG port. Host Port is for USB2.0 host controller; OTG port is for USB2.0 part of USB3.0 OTG controller, and as a part to construct a fully feature TypeC subsystem. The USB2.0 vbus gpio is board specific, it's no same with all rk3399 boards, so move it into evb voard.
