   2
   3 Required properties:
   4  - compatible: Should be one of the following:
   5    - "microchip,mcp2510" for MCP2510.
   6    - "microchip,mcp2515" for MCP2515.
   7    - "microchip,mcp25625" for MCP25625.
   8  - reg: SPI chip select.
   9  - clocks: The clock feeding the CAN controller.
  10  - interrupts: Should contain IRQ line for the CAN controller.
  11
  12 Optional properties:
  13  - vdd-supply: Regulator that powers the CAN controller.
  14  - xceiver-supply: Regulator that powers the CAN transceiver.
  15  - gpio-controller: Indicates this device is a GPIO controller.
  16  - #gpio-cells: Should be two. The first cell is the pin number and
  17                 the second cell is used to specify the gpio polarity.
