Did I forget to configure a certain item in the kernel?

Hi,

on my BBB runs Gentoo Linux with Robert Nelsons kernel 3.8.13.

Under

    /sys/kernel/debug/pinctrl/44e10800.pinmux

there are virtual files which shows the current configuration of
the gpio pins.

But it seems, that there is something missing...

beagleboneblack:pinctrl/44e10800.pinmux>head gpio-ranges
GPIO ranges handled:

beagleboneblack:pinctrl/44e10800.pinmux>head pinconf-pins
Pin config settings per pin
Format: pin (name): configs
pin 0 (44e10800):
pin 1 (44e10804):
pin 2 (44e10808):
pin 3 (44e1080c):
pin 4 (44e10810):
pin 5 (44e10814):
pin 6 (44e10818):
pin 7 (44e1081c):

For this two files there is a ':' which follows nothing.

Is this ok? Or is there any CONFIG_* missing in my kernel setup?

Best regards,
mcc
