Are these different devices? What does it mean here "instance"? What are
the differences?

And items. You do not have here multiple choices and items.

I have doubts you describe actual one GPIO controller...

Weird indentation. Use 4 spaces for example indentation.

Broken indentation and unnecessary line break before.
