Merge branch 'for-davem' of git://gitorious.org/linux-can/linux-can-next 



Marc Kleine-Budde says:

====================
the fifth pull request for upcoming v3.6 net-next cleans up and
improves the janz-ican3 driver (6 patches by Ira W. Snyder, one by me).
A patch by Steffen Trumtrar adds imx53 support to the flexcan driver.
And another patch by me, which marks the bit timing constant in the CAN
drivers as "const".
====================
