I disagree (and I also know that in the end is your call to take patches
or not and I will just accept your decision whatever it is).
What you are asking here is to not use any binding that was not already
converted from txt to yaml, I do not think it is fair to force this
decision just for TI DT files.
I'd like also to add that a conversion to yaml of this binding is in the
work [1] and this DT is compliant with it.
What's DT maintainers opinion on this matter? Rob recently provided
feedback on TPM bindings txt to yaml conversion so it should be fresh on
his mind.
