I just recalled that I created the directory,
Documentation/devicetree/bindings/arm/uniphier/

So, perhaps, it should go to

Documentation/devicetree/bindings/arm/uniphier/uniphier.txt

This is sorted in the chronological order.

I already put some bindings sorted chronologically
(for example, Documentation/devicetree/bindings/clock/uniphier-clock.txt)


(If the alphabetical sort is highly recommended,
I will do so, but I do not know what to do for the existing ones.)

OK, will do.
