Marc Kleine-Budde says:

====================
this is a pull-request for net-next/master. It consists of two patches
by Fabio Estevam, cleaning up the flexcan driver (remove default
pinctrl and switch to SIMPLE_DEV_PM_OPS). A patch by me to simplify the
Kconfig [1] handling for flexcan. And a patch by Jingoo Han that
converts the can drivers to use platform_{get,set}_drvdata().

[1] My patch touches arch/{arm,powerpc}, so I collected Acked-bys from
Arnd Bergmann, Shawn Guo and Benjamin Herrenschmidt.
