Kernel version: 3.10

Is there any way to configure default settings for some of the gpios
eventhough there is no one driving them? I am also trying to configure
some of the gpios as irq lines using just the device tree without
writing any device driver for it as it will be used by userspace.

I looked into the existing kernel code in 3.10 kernel and couldn't
find out any reliable way to do that? I did find out some pinctrl
hogging patches but that is part of latest kernel.

Just to workaround this problem I have created a dummy driver
specifically for this purpose. Is there any better way?

Thanks,
