Sure, I'll take it through my tree. I have to figure out which patch on my tree is breaking Tom's board, but once I get that figured out, I'll be pulling things in. I see it is already delegated to me in patchwork.

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.

I didn't run this on any board - it is just fixing logic there.
Just look at the code that this. ofnode_read_u32_default(node, "ti,clk-output-sel",
is using node. But node variable is not initialized at that time. It initialized below this. It means I expect that this read will always setup default value no matter what you have in ti,clk-output-sel property.
Thanks, Michal
