Actually it is not defconfig it is the entire socfpga gen5 file this patch
points to.

Let me explain a bit. At first I suspected it was the WDT driver and settings.
But I am wrong. Even turning off all dts and WDT it still has trigger fail
calibration. So now my guess has failed, but why?

I diff a bit by turning on WDT and before that the diff shows CYCLIC.
Then by default the CYCLIC somehow removes the timeout?

So I am going to re-patch this patch as reference. Then you can enclose
it in another patch.
