The subject makes no reference that this binding is for Ingenic GPIO.
Also, drop the "Documentation: " part. It's redundant.

Drop this please. This is a Linuxism.

Some h/w doesn't have interrupt capability? If not, this should not be
optional.

Just document #interrupt-cells and its value and drop this paragraph.
