Subject: [PATCH v2 6/9] dt-bindings: phy: add binding for Allwinner USB3 PHY
Date:   Fri,  6 Jul 2018 23:38:02 +0800
Message-Id: <20180706153805.25842-7-icenowy@aosc.io>
In-Reply-To: <20180706153805.25842-1-icenowy@aosc.io>
References: <20180706153805.25842-1-icenowy@aosc.io>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The new Allwinner H6 SoC contains a USB3 PHY that is wired to the
external USB3 pins of the SoC.

Add a device tree binding for the PHY.

Splitted from the PHY driver patch in v1.

+Allwinner sun50i USB3 PHY
+-----------------------
+
+Required properties:
+- compatible : should be one of
+  * allwinner,sun60i-h6-usb3-phy
+- reg : a list of offset + length pairs
+- #phy-cells : from the generic phy bindings, must be 0
+- clocks : phandle + clock specifier for the phy clock
+- resets : phandle + reset specifier for the phy reset
+
+Optional Properties:
+- phy-supply : from the generic phy bindings, a phandle to a regulator that
+	       provides power to VBUS.
+
+Example:
+	usb3phy: phy@5210000 {
+		compatible = "allwinner,sun50i-h6-usb3-phy";
+		reg = <0x5210000 0x10000>;
+		clocks = <&ccu CLK_USB_PHY1>;
+		resets = <&ccu RST_USB_PHY1>;
+		#phy-cells = <0>;
+		status = "disabled";
+	};
