 * If platform data are used you should have similar definitions

 *   static struct cc770_platform_data myboard_cc770_pdata = {
 *           .osc_freq = 16000000,
 *           .cir = 0x41,
 *           .cor = 0x20,

 *   };
 *
 * Please see include/linux/can/platform/cc770.h for description of
 * above fields.
 *
 * If the device tree is used, you need a CAN node definition in your
 * DTS file similar to:
 *
 *   can@3,100 {
 *           compatible = "bosch,cc770";
 *           reg = <3 0x100 0x80>;
 *           interrupts = <2 0>;
 *           interrupt-parent = <&mpic>;
 *           bosch,external-clock-frequency = <16000000>;
 *   };
 *
 * See "Documentation/devicetree/bindings/net/can/cc770.txt" for further
 * information.
