Hi Michal,

> There is a need to fill node before clk_output_sel is setup.

Could you be more specific about this issue ?

I assume that the issue is on a system where Xilinx is used. I did my
work/testing on a system where TI's SoC was used instead, so I'm curious
what are the problems on Xilinx.

Thanks in advance.
