I sort of like the idea, but I want a solid use case, i.e. an indication
of platform using this, and patches in the works. So I want atleast
one more patch making real use of the mechanism, or we just
gain weight in the kernel for no use.

Also, the introduction message should be merged into
Documentation/gpio.txt so people can easily find it.

I'd ideally like Grant's feedback on this too, since it's a major thing.

Yours,
