gpio device not available

[Ronald Klop]

Hello,

Running this beast of a machine. :-)
FreeBSD 11.0-CURRENT #15 r294908M: Wed Jan 27 18:46:10 CET 2016
     root at sjakie.klop.ws:/usr/obj-arm/arm.arm/usr/src-arm/sys/SHEEVAPLUG arm

I see gpio0 in dmesg:
gpio0: <Marvell Integrated GPIO Controller> mem 0x10100-0x1011f irq  
35,36,37,38,39,40,41 on simplebus0

But no /dev/gpio* thingy.

Is it possible to do anything with this gpio on my Sheevaplug?

Regards,
Ronald.
