Nobody really seriously ATM. One of the main issue is that the darwin
driver abuses apple "do-platform-*" shit. It's a mecanism they invented
to put sort-of "scripts" (in binary form) in the device-tree that can
contains elementary ops such as write GPIOs, I2C, etc...

This is extremely messy and difficult to parse. I have written the
basis for parsing them, but interpreting them is even more shitty as
the actual implementation of each ops sort-of depends on the target

It's really a piece-of-shit imho.

So we could go that way and complete my "interpreter" or just hard code
all of the GPIOs we need in the driver hoping apple don't shuffle them
too much in upcoming models...
