Hello,

this is my upcoming pull request to David. Ira, I had a trivial conflict
while merging your patches. Further I improved the ican3_to_can_frame and
can_frame_to_ican3 functions. The helper "get_can_dlc()" is to limit the
dlc value coming from the controller, further only dlc bytes are copied
from and to the controller, not the whole frame. (see patch 5/9).

This pull request will also contain the flexcan update for imx53 and the
bittiming_const annotation posted earlier this week.

Pleae review and test.
Feel free to send Acked-by, Tested-by, Reviewed-by etc :)

regards, Marc
