+* Microchip MCP251X stand-alone CAN controller device tree bindings
+
+Required properties:
+ - compatible: Should be one of the following:
+ - "microchip,mcp2510" for MCP2510.
+ - "microchip,mcp2515" for MCP2515.
+ - reg: SPI chip select.
+ - clocks: The clock feeding the CAN controller.
+ - interrupt-parent: The parent interrupt controller.
+ - interrupts: Should contain IRQ line for the CAN controller.
+
+Optional properties:
+ - vdd-supply: Regulator that powers the CAN controller.
+ - xceiver-supply: Regulator that powers the CAN transceiver.
+
+Example:
+ can0: can@1 {
+ compatible = "microchip,mcp2515";
+ reg = <1>;
+ clocks = <&clk24m>;
+ interrupt-parent = <&gpio4>;
+ interrupts = <13 0x2>;
+ vdd-supply = <&reg5v0>;
+ xceiver-supply = <&reg5v0>;
+ };
