+Texas Instruments TCAN4x5x CAN Controller
+================================================
+
+This file provides device node information for the TCAN4x5x interface contains.
+
+Required properties:
+	- compatible: "ti,tcan4x5x"
+	- reg: 0
+	- #address-cells : 1
+	- #size-cells : 0
+	- spi-max-frequency: Maximum frequency of the SPI bus the chip can
+			     operate at should be less than or equal to 18 MHz.
+	- data-ready-gpios: Interrupt GPIO for data and error reporting.
+	- wake-up-gpios: Wake up GPIO to wake up the TCAN device
+
+See Documentation/devicetree/bindings/net/can/m_can.txt for additional
+required property details.
+
+Optional properties:
+	- reset-gpios: Hardwired output GPIO. If not defined then software
+		       reset.
+
+Example:
+tcan4x5x: tcan4x5x@0 {
+		compatible = "ti,tcan4x5x";
+		reg = <0>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+		clocks = <&tclkin_ck>;
+		spi-max-frequency = <10000000>;
+		data-ready-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
+		wake-up-gpios = <&gpio1 17 GPIO_ACTIVE_LOW>;
+		reset-gpios = <&gpio1 27 GPIO_ACTIVE_LOW>;
+	};
