* Renesas RH850 CAN *



This driver implements spi slave protocol for rh850 can controller



Required properties:

  - compatible: Should be "renesas,rh850"

  - reg: Should contain spi chip select

  - interrupt-parent: Should specify interrupt controller for the interrupt

  - interrupts: Should contain IRQ line for the CAN controller

  - spi-max-frequency: Should contain maximum spi clock frequency for

                       slave device



Example:



	can-controller@0 {

		compatible = "renesas,rh850";

		reg = <0>;

		interrupt-parent = <&tlmm>;

		interrupts = <127 0>;

		spi-max-frequency = <5000000>;

	};
