As you can see, I've pretty much come full circle on the adding
'automatic' OF support to gpio chips.  Originally (as you well know) I
was strongly opposed to any addition of OF code to the core gpiolib.
All of the notifier work was a response to that.

However, now that I actually have played with the code and looked and
the issues deeply, I've got an entirely different opinion.

ROFL :-D

(The fact
that OF support is being ported to more architectures is also a
factor.)

Yeah, I guess without multi-arch OF effort such an OF+gpiolib
integration would be very dubious. But as OF spreads to other
architectures, and we already have of_node in the 'struct
device'... I guess that makes sense now.

Anyway, please take a look.

It works here with some small fixes (patches on the way).

Tested with MCU (I2C), and QE GPIO (memory mapped) GPIO controllers.

Thanks!
