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.

	- device-wake-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.

	- device-state-gpios: Input GPIO that indicates if the device is in

			      a sleep state or if the device is active.



Example:

tcan4x5x: tcan4x5x@0 {

		compatible = "ti,tcan4x5x";

		reg = <0>;

		#address-cells = <1>;

		#size-cells = <1>;

		spi-max-frequency = <10000000>;

		bosch,mram-cfg = <0x0 0 0 32 0 0 1 1>;

		data-ready-gpios = <&gpio1 14 GPIO_ACTIVE_LOW>;

		device-state-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;

		device-wake-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;

		reset-gpios = <&gpio1 27 GPIO_ACTIVE_LOW>;

};
