Set GPIO pin direction in DTS

How can I set GPIO pin direction to output in the .dts ?
Currently gpioinfo shows the lines I need as inputs:
line 13: unnamed unused input active-high
I only need to set the direction and not the value, the plan is to control the pins in a new manner with gpioset (not echo and sysfs).
I'm currently using RBM33G and here is the non-modified dts file.
