Hi All,


I am using yocto 1.6 daisy branch with kernel 3.10.17.

I am able to configure all platform data and pin-muxing correctly.


I have a query in that... How can we configure a GPIO that is Input/output in device tree?

I didn't find anything in device tree.

I have two GPIO in which one is input and other output, i am able to configure everything successfully.

But need to ask where i can define those pin as Input or Output ... In device tree? ... or ... in board file? ... or in driver?
