+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
+
+Optional properties:
+ - clocks: Processor clock phandles (see clock bindings for details)
+ If no clock is defined then the default 40MHz freq is set.
+ - 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>;
+ };
