From mboxrd@z Thu Jan 1 00:00:00 1970 From: Amelie Delaunay Subject: [PATCH v4 1/2] dt-bindings: usb: ehci: add optional external vbus supply property Date: Thu, 1 Mar 2018 10:51:38 +0100 Message-ID: <1519897899-8577-2-git-send-email-amelie.delaunay@st.com> References: <1519897899-8577-1-git-send-email-amelie.delaunay@st.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1519897899-8577-1-git-send-email-amelie.delaunay@st.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Greg Kroah-Hartman , Rob Herring , Mark Rutland , Tony Prisk , Alan Stern , Roger Quadros , Felipe Balbi , Robin Murphy Cc: devicetree@vger.kernel.org, Amelie Delaunay , linux-usb@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org On some boards, especially when vbus supply requires large current, and the charge pump on the PHY isn't enough, an external vbus power switch per port may be used. Add portN_vbus-supply property to usb-ehci bindings. As the number of ports depends on the ehci controller, and the port on which an external vbus supply depends on the platform, is used to make it generic.
