Hi Sascha,
the gpiolib support on mxc seems to lack protection against concurrent
access. Is it OK for this SOC family?
Regards.

http://git.pengutronix.de/?p=imx/linux-2.6.git;a=commitdiff;h=14cb0de
is on it's way into mainline. Note that you need
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6280/1
on top of it.
Does this answer your question?
Best regards
Uwe
