I want to use dcan0 and followed this lead:
http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/#comment-152

To build the latest kernel I followed the instructions on this github page. Further I disabled my i2c2 pinmux by commenting out in am335x-bone-common.dtsi
//pinctrl-0 = <&i2c2_pins>;

And enabled dcan0
&dcan0 {
status = "okay"; // Switch on DCAN0
pinctrl-names = "default"; // Apply default pinmuxing
pinctrl-0 = <&dcan0_pins>;
};

And added pinmux to the am33xx-pinmux
dcan0_pins: pinmux_dcan0_pins {
pinctrl-single,pins = <
0x178 0x12 /* dcan0_tx, SLEWCTRL_FAST | PULLUP | MODE2 /
0x17C 0x32 /
dcan0_rx, SLEWCTRL_FAST | INPUT_PULLUP | MODE2 */
>;
};

Unfortunately I get the following message:
platform 481cc000.d_can: alias fck already exists

Is this due to having I2C2 and dcan0 enabled?
