Kernel Oops in new fmcomms2-3 device tree

I have created a new linux image with the recently updated device tree for fmcomms2-3 on Xilinx VC707.

 

I believe, there might be a small bug in the new device tree.

 

I receive a kernel Oops as can be seen:

 

RPC: Registered tcp NFSv4.1 backchannel transport module.

XGpio: /amba_pl/gpio@40000000: registered, base is 480

How could I fix this issue? I don't receive a kernel Oops with the previous device tree.

Max
